A man has been arrested following a sex attack on a three-year-old girl in a country park on the Isle of Wight.
The incident took place in a wooded area of Fort Victoria Country Park, Yarmouth, shortly after 3pm on Monday, police said.
It is understood that the suspect, aged in his sixties, is not known to the child or her family.
Detective Chief Inspector Liam Davies said: "This was a very serious incident and there will be an increased police presence in the area whilst we examine a number of lines of enquiry.
"The child, a three-year-old girl, and their family are receiving specialist support while we seek to establish the full circumstances of what happened.
"We know there were two dog walkers in the vicinity at this time - a man and a woman - who we believe may have witnessed something significant and discussed this with the child's mother.
"It is vital that we identify them.
"In addition, we would like to hear from anyone who used Fort Victoria Country Park either that day or previously and who may have seen someone acting suspiciously, or anything out of the ordinary which could assist our investigation."
