The Indian Coastguard and Navy along with the police have launched a joint drill to test their preparedness in dealing with 26/11 type terror attacks.
Under the drill, codenamed 'Operation Rakshak' which was launched on Sunday night, five coastguard sailors disguised as "terrorists" tried to "intrude" into Chennai and were 'nabbed' by police in Chennai on Monday. They were later taken for "interrogation".
The drill, aimed at preventing terror strikes both from land and sea, follows a similar operation recently, titled 'Operation Barricade,' the police said.
The CG sailors disguised as terrorists were taken into custody near the harbour while trying to sneak in to attack 'potential targets,' the sources said.
The police stepped up security across the state as part of the drill.
Following the Mumbai terror attacks [ Images ] in November last year, when the perpetrators had come through the sea route, state police in association with other security agencies including CG and Navy had decided to conduct such drills to check their preparedness in guarding the state's 1,076 km coastline.
