Roughly 20 South Korean tourists were injured in Thailand over the weekend in a speedboat accident.

Local officials say the boat carrying 28 South Koreans was struck by another speedboat in the Thai resort city of Pattaya around 10 a.m. Sunday.

A 51-year-old surnamed Hong lost a leg and a 63-year-old Kim sustained a serious fracture. Six others were seriously injured while 14 sustained minor injuries.

The group was headed into the Pattaya coral island when the accident occurred.

Local police are searching for the driver of the boat who fled after the collision with the boat of the Korean tourists.
