OKLAHOMA CITY - New details surround a ten hour standoff Wednesday night, with a bondsman and the Oklahoma City police tact-team.

Police said a man with a gun ran from the bondsman and held himself up inside a home near Southwest 23rd and Brookline.

Court records show 41-year-old Bruce Cass is no stranger to law enforcement.

Right now, he has an ongoing assault and battery case out of Oklahoma County.

“Right when I come out the door, there was like four swats like right in front of our house, with the big shot guns,” said neighbor, David Richardson.

Richardson and his family have lived across the street from the standoff scene for about 20 years.

“Nothing like this has ever happened,” said Richardson. “I mean it was bad. I mean it was scary.”

A bail bondsman was trying to take Cass into custody, but Cass ran back inside the home and refused to come outside.

That's when the stand-off began.

“They were busting out the windows. We were expecting them to come out shooting at any time,” said Richardson.

And neighbors said, Cass didn't even live at the home. Neighbors think he was at the home to see a friend.

According to police, Cass has a history of violent behavior and an extensive criminal history.

Officers made entry and said they found Cass "armed with a pocket knife barricaded inside of a closet." Then, an "officer tried tasing him" but it didn't work. So the tact team backed out and more help was called.

Cass could be seen through a window with "a pocket knife to his throat" and "a cell phone in the other hand."

It appeared he was on a call with someone.

“They were like, we know you're armed, just come on out. They gave him a hundred chances, and he wasn't having it,” said Richardson.

Police said they continuously gave verbal commands asking Cass to surrender.

Ten hours later, they found him sleeping under a mattress.

“There are so many crazy people,” said Richardson. “You never know who's right across the street.”

Police said Cass also had a gun inside the home. Fortunately, no one was injured.
