The measure, based on a concept of prisons minister - Chandrasiri Gajadeera, is already being planned out.

Speaking, the media spokesperson of the Prisons commissioner - Thushara Upuldeniya says that the drugs smuggled in for the daily use of prisoners are brought in slight quantities. Therefore, the possibility of them being undetected by scanners, is high, he added.

Training for the purpose is to be done by the divisional units in Asgiriya and Kandy of the Sri Lankan Police kennels.
