A sick bat that was surrendered to a police beat has scratched an officer and prompted an urgent search for the two teenagers who handed in the animal.

It has been confirmed the bat was suffering from the potentially deadly Australian bat lyssavirus, according to Metro North Public Health Unit.

Health officials are urgently seeking two teenagers - a boy about 14 years old and a girl about 16 years old - who anonymously handed in the bat to Kippa-Ring police beat, north of Brisbane.

Public Health physician Dr Catherine Quagliotto said the bat was surrendered on Tuesday morning and was subsequently found to have Australian bat lyssavirus after scratching the police officer on duty.

"We need to get in touch with these teenagers immediately to ascertain if they were bitten or scratched by the bat or if anyone else was exposed," Dr Quagliotto said late on Wednesday.
