Police Commemoration Day 2014 is an occasion to remember the valiant police personnel, who gave their lives defending the peace and security of people in society. The Telangana Police in Hyderabad gave a sense of might to the people and young students at Gymkhana Grounds on Monday by demonstrating use of several weapons and tools they regularly use. The Police explained to children about different types of weapons, water cannon and tear gas shells during an Open House programme. Hyderabad Commissioner of Police M Mahendar Reddy had a look at different weapons. The Hindu photographer Nagara Gopal captured a few glimpses of the demonstration.
