An individual was arrested for assaulting a police officer in Embilipiiya town.
The arrested man is working at Mechanical Engineer Corps in Sri Lanka Army, police said.
The man is believed to be a close friend of Sumith Prasanna who died during a police clash in a party in Embilipitiya area last month.
A group assaulted a young police constable who was transferred from Embilipitiya to Pindeniya Police in Kegalle. The constable was thus attacked when he was returning home on Sunday (14) night.
The assaulters fled the area after this incident.
