Long Beach firefighters were called to the Peninsula to help a woman who’s leg was stuck in a sinkhole Wednesday evening, a fire official said.

The woman was working some type of construction along the waterline when she got stuck just before 5:40 p.m. near 55th Place and East Ocean Boulevard, LBFD spokesman Jack Crabtree said. As the tide was coming in and the sun was going down, she accidentally stepped in a small sinkhole on the beach, submerging one leg just past her knee.

Lifeguards immediately tried helping to dig her out, but the rising tide kept refilling the hole, Crabtree said. At one point 13 firefighters were assisting marine safety personnel on the call, Crabtree said. They were able to dig her out at about 6 p.m.

The woman was assessed at the scene for hypothermia and released, he said.
