An alleged thief was arrested today after a chase and a fight by two constables posted in northwest Delhi's Swaroop Nagar police station. Constables Pawan and Ratan Lal were out patrolling in the morning when they spotted two motorcycle-borne men fleeing after snatching a truck driver's mobile phone, the police said.

The constables followed the accused and intercepted them. While one of the men managed to escape, the other, identified as Sajid, got into a fight with the policemen and pushed Lal into a drain, the police said.
