Thames Valley Police in Milton Keynes have released CCTV images of a man and two people walking a dog, they would like to speak to in connection with nine arsons.

The two most recent arsons took place on Saturday (15/5), around 3am, in New Bradwell, where a white Renault Traffic was set on fire in Harwood Street and a blue Peugeot 307 was set on fire in Church Street.

These arsons are believed to be connected to the arsons carried out on Saturday 17 April, where seven vehicles were set on fire in New Bradwell. The damaged vehicles were located in Harwood Street, Stantonbury Close, Thompson Street, Earls Willow, Spencer Street and Bounty Street in New Bradwell.

Due to the close proximity of all the fires, police believe they are linked to the same offender.

The man pictured is white, 5ft 10ins and he was wearing black jogging bottoms, a black jacket, black and white trainers, a red baseball cap and he was possibly carrying a black rucksack.

The three people pictured include the man pictured in the additional CCTV still, another person who was wearing camouflage-style khaki, three quarter length shorts; a black hooded top and black shoes and the third person is believed to be a young child, dressed in all black with a white Westland Terrier dog.

Police are appealing for anyone who recognises the people pictured to contact them as they are keen to speak to them in connection with the arsons.
