People at an illegal betting centre in Dankotuwa were rounded up by the police last evening.
Police reports indicate that around 20 people were gambling at the spot when the police stormed the premises.
Most of the perpetrators had managed to escape but police were able to apprehend one individual.
In the subsequent scuffle that took place between a police officer and the suspect, the officer’s weapon is said to have gone off accidentally, injuring the man.
The suspect was admitted to the Negombo hospital.
