Police have issued a desperate appeal after a three-year-old girl was seriously sexually assaulted in a county park.
Detectives have arrested a man in his 60s following the attack at Fort Victoria Country Park in Yarmouth on Bank Holiday Monday just after 3pm.
They have pleaded for witnesses to come forward after a three-year-old was assaulted in a wooded area.
A man in his 60s from the Isle of Wight has been arrested and remains in custody, police said.
Police said the victim and her family are receiving specialist support.
And they have appealed for a pair of dog walkers to come forward as they might have vital clues about the attack.
Police said the "smallest bit of information" could prove vital to the investigation.
Detective Chief Inspector Liam Davies said: “This was a very serious incident and there will be an increased police presence in the area while 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. If this is you, please contact us immediately.
“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.
“You may not believe that you have anything significant to tell us, but even the smallest piece of information could be vital, so please get in touch.”
Police said increased numbers of officers will be patrolling the park following the attack.
Superintendent Sarah Jackson said: “Incidents of this nature are extremely rare, and we work very hard on the Isle of Wight to tackle sexual offences in partnership with organisations that support victims.
“All allegations of this nature are taken very seriously, and dedicated officers will be working tirelessly to investigate this incident.
“Officers remain at the scene in Fort Victoria Country Park, and there are additional officers in the area conducting patrols, so if you have any information or concerns please do not hesitate to approach them.”
Anyone with information is asked to contact police on 101, quoting Operation July.
