Police said Suresh and his friend sped away on their two wheeler last night at a checkpost at Chennimalaipalatyam on the district border though police signalled them to stop
Police gave chase for about four km.
The speeding Suresh rammed his bike on an electric post, killing him on the spot and resulting in serious injuries to his friend, they said.
They refused to allow police take the body in an ambulance unless they were assured of action against the policemen and adequate compensation to the family of the deceased man.
The protesters dispersed later after police assured them that suitable action would be taken.
