Toledo, Ohio (AP) -- The Toledo Zoo says a tiger reached through a double mesh barrier and injured a zookeeper, sending the keeper to the hospital with three lacerations to the chest.

Zoo officials say the employee was doing normal rounds at about 8:30 a.m. on Sunday and was in an area where he had worked before without any problems.

The zoo says one its two female tigers was somehow able to get a paw through the mesh at an odd angle. The keeper was treated and released at a local hospital.

The zoo was not open at the time of the incident. Spokeswoman Andi Norman says officials are reviewing whether the zoo needs to make changes to the tiger exhibit.
