Kasargod Circle Inspector P K Sudhakaran told reporters that those involved in the robbery have been identified and would be arrested within a few days. A six gram gold chain dropped by the fleeing robbers has been recovered from near the bank, he said.
Police said they have decided to extend the probe into the case to Karnataka as they suspect the burglars might have have fled to Mangalore with the help of some local residents.
A woman staffer who resisted their attempt was injured and has been hospitalised.
