Police cadets learnt about the work of the Met's canine unit with a visit from one of the force's four-legged friends.
Harrow Volunteer Police Cadets, who meet at Harrow High School, were visited by police dog Chip and his handler PC Jill Fletcher and Inspector Paddy O'Hara.
The cadets learnt about the dog support unit and were given a demonstration of how PD Chip tackles a suspect.
Youth engagement co-ordinator PC Simon Underwood said: "This was a fantastic evening and the DSU did us proud in particular 'PD Chip' who was naturally the star of the show and is a real credit to Jill his handler.
"To say the cadets enjoyed the evening is an understatement and it enabled them to have a real insight into not only what immense capabilities the police dogs have in supporting officers on the street, but also the effort and training that goes into being a police dog handler.
"Evenings like this are so important for young people and help immensely for them to better understand the different strands of policing."
The Volunteer Police Cadets is a uniformed voluntary youth organisation supported by the Metropolitan Police and has branches all over London.
There are a junior group for children from the age of ten to 13 and senior police cadets, made up of teenagers from the age of 14 to 19.
