Thames Valley Police is appealing for witnesses after an 11-year-old boy was subjected to a sex attack in Wendover. Officers said the youngster was walking in Bacombe Lane, close to a bridleway when a man approached him and assaulted him, before running off.
Neighbourhood patrols are taking place in the area and enquires are ongoing.
The offender is described as a white man aged approximately 40, with stubble on his face. He was wearing a grey and black diamond-patterned hooded top, dark blue jeans and black shoes.
Det Insp Ben Gasson said: “I am appealing for anyone who saw a man matching this description or anyone seen acting suspiciously in this area to contact police.
“The victim was not hurt during the incident but has understandably been left shaken."
Police say they are hunting for a man who carried out a sexual assault on a young woman in Eastbourne.
On Thursday, at about 8.40pm, the local woman was walking home from work along St Philips Avenue when she stopped and sat on a wall outside the electricity sub-station to make a phone call.
While there, she was approached four times by a young man on a BMX-style cycle, who threatened her and then carried out a sexual assault, before eventually riding away.
Nothing was stolen and the victim did not require medical treatment. Police say they are looking for witnesses to come forward.
The suspect is described as tanned, about 17, with dark hair and a fringe across his face. He was wearing a red black and grey checked hooded top.
Officers say they are not linking the attack with three similar assualts in the town during September, but the "possibility is being borne in mind".
