Chicago police arrested one of their own Thursday night after she allegedly got violent with an officer executing a search warrant.
Sources said the warrant was related to a drug investigation.
Drug paraphernalia and two 9 mm handguns -- one of them loaded and discovered in a nightstand -- were found inside the residence, in the 5000 block of South Lacrosse Avenue, sources told NBC Chicago.
Once inside the home, police said the woman struck an officer. They learned she was an off-duty officer while they were in the process of arresting her.
Police also arrested a man during the search. Albert Quiroz, 41, is a convicted felon and was in possession of a firearm, police said.
Quiroz was charged with one count of unlawful use of a weapon by a felon. His bail was set at $150,000.
A law enforcement official with knowledge of the investigation says Quiroz is a reputed gang member with the Satan Disciples.
He has prior felony convictions from 1997, 1994 and 1995.
The woman was charged with aggravated battery to a police officer. She's been relieved of her police powers during an internal investigation.
