A Japanese bear is on the run after injuring four people.

Japanese authorities are trying to capture a bear in northeast Japan after it injured four people and was arrested after opening a window on its own.

Previously released footage shows a bear chasing and attacking a man outside a building in Fukushima.

The bear was then locked in an electronics factory but escaped during the night, officials said.

A bear’s tracks indicated he had loosened the window shutters and pushed them away, city officials said.

The bear was reportedly seen opening a water faucet with its paw before its escape on Wednesday.

“We believe it’s very smart,” Fukushima Mayor Yuki Baba said, according to the Kyodo news agency.
