Brazil Ex-Policeman Allegedly Sold Gang 10 AR-15 Rifles

BRAZIL · SECURITY

Prosecutors say serving and former officers also sold confidential police data to criminals.

A ring of Rio police and ex-officers allegedly sold weapons, including US-designed AR-15 rifles, to a Rio gang boss. Brazil’s Federal Police and Rio state prosecutors launched Operation Magen against the group on Wednesday, 7 October.

For US readers, the charges describe rifles of American design moving from police and former officers to a drug faction. Prosecutors also asked for the arrest warrants to be entered into Interpol’s system, citing a risk that suspects could flee Brazil.

Five people were arrested, Globo’s news site G1 reported. The gang’s leader and a serving civil police officer remain at large.

What Prosecutors Say the Ring Sold

The Federal Police is Brazil’s national investigative force. It ran the case with GAESF, a tax-evasion and integrity unit of the Rio de Janeiro state prosecutors’ office, known as MPRJ.

Investigators say a former military police officer led the ring. In October 2022, he allegedly carried and sold 10 AR-15 rifles to the gang boss.

Brazil’s military police are state forces that patrol the streets, not army units. A second former military police officer is accused of supplying two Colt M4 rifles and four magazines for resale.

A serving military police officer allegedly offered a revolver, nine Glock 9 mm pistols and 22 magazines for sale. The Federal Police said the group also took rifles and police equipment as commission or payment.

G1 reported that the group allegedly traded at least 22 weapons with the gang leader, including 13 rifles. The case began with a Federal Police probe into the firepower of traffickers in the Complexo de Israel, prosecutors say.

Leaked Police Data and Millions in Transactions

Prosecutors say officers used restricted police systems to look up vehicle owners, addresses, locations and arrest warrants. In one case, a civil police officer allegedly told the ring where a wanted man was, so it could reach him first.

Prosecutors believe the aim in that case was extortion. Brazil’s civil police are state detectives who investigate crimes.

The Federal Police says the scheme moved over 100 million reais (about US$20 million) in four years, partly through shell firms. Prosecutors found more than 250 million reais (about US$50 million) in transactions by individuals and five linked companies.

Prosecutors say they obtained a freeze on assets and asked for three properties and 31 vehicles to be seized. Conversions use the Central Bank of Brazil’s PTAX rate for 7 October, 4.99 reais per US dollar.

Several suspects held public posts, including appointed jobs in Rio’s state legislature and at the state vehicle agency, Detran. G1 reported that some had been expelled from the military police before getting those jobs.

GAESF prosecutor Bruno Humelino said the shift of state agents into organised crime had caught his office’s attention, G1 reported. Detran said suspects who worked there have been dismissed.

A former legislative aide was arrested with a rifle in his room at a Barra da Tijuca seafront hotel, G1 reported. He was not booked over it or a second rifle at home, as he showed a collector and sport shooter registration.

The Rio Gang Boss at the Centre of the Case

Prosecutors name the alleged buyer as Álvaro Malaquias Santa Rosa, known as Peixão. They describe him as the leader of the Terceiro Comando Puro in the Complexo de Israel.

The Terceiro Comando Puro, or Pure Third Command, is a Rio gang that trades drugs. The Complexo de Israel is a cluster of favelas in the city’s North Zone.

Peixão was also charged in the case, prosecutors say. He remains a fugitive, G1 reported.

What It Means for You

For travellers, the US State Department rates Brazil at Level 2, exercise increased caution. It rates favelas at Level 4, do not travel, even on guided tours.

The Complexo de Israel lies in Rio’s North Zone, away from the main beach districts. Yet one arrest took place in a seafront hotel in Barra da Tijuca, a district popular with visitors.

For readers following US gun policy, the charges centre on AR-15 rifles, a US design, and Colt M4 rifles. Connecticut-based Colt makes the M4 carbine for the US Army, Stars and Stripes reported in 2024.

Prosecutors have not said where these rifles were made or whether any came from the United States. An Interpol listing would alert police in member countries if the suspects travel abroad.

What Is Not Known

Prosecutors have not said how the rifles entered Brazil or who sold them to the ring. The whereabouts of the gang leader and the fugitive civil police officer are unknown.

The official statements do not give an arrest count; the figure of five comes from G1. The Federal Police and prosecutors also give different money totals without explaining the gap.

G1 sought comment from lawyers for three suspects but had no reply by its last update. G1 could not reach lawyers for the other suspects.

What Comes Next

The case runs before Rio’s 1st Organised Crime Court, which issued the warrants. Charges include armed criminal organisation, illegal arms trading, breach of official secrecy, usury and money laundering.

Rio’s civil police opened a disciplinary case against the officer at large; the military police said it would review its officer. The arrests do not establish guilt, and all suspects are presumed innocent.
