A decision to this effect was taken yesterday at a high level tourism security committee meeting which was chaired by state tourism minister Dilip Parulekar.
Beaches like Baga, Anjuna, Calangute, Colva and others which are popular and have the highest footfalls will be given security cover till midnight, Parulekar told PTI.
India Reserve Battalion (IRB) has been deployed at the beaches in addition to the Tourism Security Force, which is currently facing manpower shortage.
The IRB will remain posted at lesser popular beaches till 10 PM, he said.
It was also decided at the meeting to strengthen Tourism Security Force, which currently has 75 personnel.
"Additional 125 personnel would be recruited in the force soon, strengthening it further," Parulekar added.
The meeting was held to review security arrangements in the backdrop of commencement of the tourist season in the coastal state.
The first chartered flight carrying Russian tourists arrived in the state on Sunday.
