DETROIT – Video from a surveillance camera in a Detroit liquor store shows the brutal attack of a 64-year-old man during an attempted robbery that happened last weekend.

Police released the video Friday with the hope that someone will recognize the three men who were involved.

The video shows the three confronting the victim Saturday evening as he stood in a liquor store in the 12800 block of Plymouth Road. One of the men said, "Give me some money," and punched the victim in the face, police said.

The video shows the victim being hit a second time while he is laying flat on the ground. The three men then exit the liquor store.

"They socked me," Ulmer said. "They knocked me out."

Police also released video of the three men leaving in a silver Dodge Caliber.

Ulmer was hospitalized for six days with 14 broken bones. He needed stitches and has a crack in his skull.

"You never know when it's going to happen," Ulmer said. "You have to watch your back at all times."

Ulmer has been released and is at home recovering.

Detroit police are investigating.

Anyone with information on the assault or the men in the videos is asked to call Sgt. Bucy at the Detroit Police Department's 2nd Precinct at 313-596-5240, or Crime Stoppers at 800-SPEAKUP.
