Mr Mehrishi, who was on a day-long visit Srinagar yesterday, on the spur of the moment decided to visit a camp of the CRPF which is involved in counter-insurgency operations as well tackling stone pelting mobs.
He gave no clue to those living in the camp in Awantipora in Pulwama district before reaching there at around 12.30 pm when the securitymen were having lunch, a security official said.
Mr Mehrishi told them that he had come to have a first hand experience about their life in Kashmir, listen to their problems while sharing the meal.
The home secretary had the vegetarian lunch comprising rajma, seasonal vegetables, roti, pickles, rice and banana, the official said.
Mr Mehrishi was apparently very happy that the food was not spicy and neither too oily.
The home secretary told the CRPF men to consider the Kashmiri youths as their "own brothers" and tackle such situations with sensitivity.
Mr Mehrishi was told that the CRPF personnel were given all necessary protective body gear and helmets.
During the 45-minute interaction, the security personnel told Mr Mehrishi that their morale is very high despite working in adverse situation in the Kashmir Valley, the official said.
