A teenage boy suffered a head injury at a Boston zoo after falling 15 feet into a pit in a lion exhibit.

Boston police Officer Joe Zanoli said the lions were secured at the time and had no contact with the 16-year-old boy.

Zanoli said the boy was removed by Boston firefighters and taken to a local hospital with minor injuries.

Boston EMS spokeswoman Jen Mehigan said the accident happened at about 3:30 p.m. She said it wasn't immediately clear how the boy got into the pit.

Movie crews have been at the zoo filming "The Zookeeper," starring Kevin James as a zookeeper with no luck at love.

A spokeswoman for the zoo did not immediately return a call for comment.
