Balwinder Singh Nezvi, the jawan, fired 18 rounds from his Insas rifle late last night injuring five persons including two women, and a police constable of Naroda Police station.
"An internal inquiry has been initiated under the supervision of DIG Y M Sharma," Deputy Commandant CISF, S N Singh, told PTI.
"CISF is meant for providing highest level of security, but if such incidents happen they need to be dealt with strictly. Hence we would be recommending highest level of punishment for the Jawan which could be dismissal from the service," Singh said.
The Dy Commandant said that Balwinder had returned from leave yesterday. He was a part of the company from Jammu and Kashmir stationed here for the protection of the post-Godhra riots victims.
"We believe he was under severe pressure following family problems. He was in heavy debt, his house was under mortgage and recently his brother had died," Singh said.
"However, the exact reason for his act is still not known. It would be ascertained after full inquiry," he added. Police said that Balwinder had been booked for attempt to murder and destruction of property.
