Federal agents and Omaha police conducted an early-morning raid, arresting nearly a half-dozen suspected gang members accused of carrying out violent crimes and illegal drug sales.

The U.S. Attorney’s office in Nebraska says police and members of the federal Bureau of Alcohol, Tobacco, Firearms and Explosives and U.S. Marshals Service conducted the operation early Wednesday morning in Omaha armed with six arrest warrants. During the raid, officers seized 41 guns – 10 of them reported stolen – and nearl two pounds of marijuana.

Authorities arrested five people, all suspected of having ties to the Trip Set gang, on a range of mostly drug and weapons counts. Police say one suspect remains at large. Authorities say six others charged in connection to the operation were already in custody when the raid was carried out.

Prosecutors say the gang is known for armed robberies, home invasions, burglaries, credit card fraud and assaults.
