Kiefer Sutherland reportedly shocked nightclub goers by grabbing their faces and squeezing their cheeks recently.

The Hollywood star is well known for his hard partying ways, which don't seem to be slowing down. Kiefer enjoyed a night out at a private nightspot in Hollywood recently, when he got up close and personal with some of the other guests.

"It was really weird and scary he'd grab hold of unsuspecting people and squish their cheeks together like silly putty to make funny faces, then scream with hysterical laughter," a source told National Enquirer.

Kiefer approached the people outside the club's lavatories, it has been claimed.

While some of the partygoers thought it was funny, others couldn't understand what was going on.

The 45-year-old star apparently kept up the game until one man got angry with him. The unidentified male apparently threatened to punch Kiefer unless he stopped, whereupon the actor and his pals left the venue to continue their night elsewhere.
