Jan. 19 (UPI) -- A 12-year-old boy was in critical condition following a shark attack off Sydney's coast, authorities said.

Emergency services were called to Hermitage Foreshore Walk near Shark Beach at about 4:20 p.m. local time Sunday in response to reports that a boy had been bitten by a shark, the New South Wales Police Force said in a statement.

The boy was rescued from the ocean by Marine Area Command and Eastern Suburbs Police. Two medical tourniquets were used on the boy as they applied first aid for what police called serious leg injuries before he was transported to Children's Hospital in Randwick in critical condition.

"The injuries are consistent with what is believed to have been a large shark," police said.
