OAK CLIFF (CBS11) – Neighbors in Oak Cliff were awakened by gunfire Thursday, from what they say sounded like an assault riffle. It was 6:15 a.m. and an undercover Arlington police officer had been shot.

“We heard like a hail of gunfire. We heard a rapid fire. boom, boom, boom, boom, boom,” says neighbor Anthony Cisneros.

“Officers from a multi-jurisdictional task force were working an operation here at the location and came under fire by an unidentified subject,” says Major Max Geron with the Dallas Police Department.

Sources tell CBS 11 the wounded officer was part of an ongoing Immigration and Customs Enforcement Investigation. A pickup truck left behind at the scene was riddled with bullet holes.

“I had seen a guy who had walked up. A black truck passed by slow and then it busted a U and pulled up to the guy. The guy’s like, ‘I think I’ve been shot. I think I’ve been shot,” says Cisneros.

Cisneros says a red truck pulled behind the vehicle carrying the officer and followed it. Then more gunfire.

“The officer was removed from the scene for the purpose of obtaining medical attention,” says Major Geron. “The officer was then transported to Methodist, where he is currently is stable condition and is expected to recover.

The SWAT Team swarmed the neighborhood – no one was allowed in, and only residents with identification could leave. Dallas police took several people into custody but wouldn’t say if they were witnesses or suspects.

“This remains an ongoing, dynamic incident,” Major Geron says.

Police say because of the sensitive, undercover nature of the case, they will not be releasing the wounded officer’s name or picture.
