Grizzly bear tries to break glass enclosure

Visitors at the Minnesota Zoo got the fright of their life on Monday when a grizzly bear tried to break its glass enclosure.

The animal picked up a baseball-sized rock and started repeatedly smashing the window, which is almost seven centimetres thick.

Staff suspect Kenai, a nearly full-grown male bear, was responsible for the attempted break-out.

Zoo Manager Tony Fisher told Fox9 he is usually the "class clown".

“He didn't know what he was doing. He was just being a bear,” Fisher said.

“It [the glass] did what it was supposed to do.”

Robin Ficker saw the whole incident from the other side.

“All of a sudden, while they were wrestling and playing, one of them picked up a very large rock," he said.

“While many people were standing there, he slammed it against the glass several times,” Ficker said.

“It had to weigh 50 pounds, and did a chest pass with that rock just like Wes Unseld used to do with the basketball into the glass."

The exhibition has been temporarily closed for repairs.
