FORT WORTH -- A north Texas drug raid on Wednesday may have taken a wrong turn, NBC 5 News reported.

A Fort Worth man, Steve Blackman, said he was shocked when the SWAT team raided his home, saying the police made a big mistake and stormed the wrong house.

The raid was at a house in a working-class neighborhood, and it involved both Fort Worth police and FBI agents.

"I didn't know what was going on until I got here and when I got here, it looked like a war zone," Blackman said. "There were SWAT teams."

Blackman said when he came home from work, he found his windows busted out, and his back door on the ground in his back yard.

"They took the door straight off the hinges," Blackman said. "There's no door."

Police and FBI agents were everywhere, but Blackman said he couldn't get a straight answer from anyone.

"Then they tried to tell me that somebody had broke into my house and I told them, 'I'm not stupid, I can see you all did these canister shots inside the house,'" Blackman said. "Then they tried to tell me somebody sold drugs out of the back yard and I said, 'That couldn't happen; I've got a dog back there. Nobody sells drugs out of this house.'"

Fort Worth police released a short written statement saying that an investigation was under way, and the FBI has not returned NBC 5's calls.

A search warrant officers later handed to Blackman said they were looking for crack cocaine and a fugitive from a recent gang crackdown, but in handwritten notes, two FBI agents admitted they found nothing.

The city is now paying to clean up the tear gas that still lingers in Blackman's home and to repair the damage. But Blackman said he's still getting the runaround from police and city leaders. "An apology or something, you know, that's what I'm saying," Blackman said.
