A man who sexually assaulted a woman out jogging in East Sussex may also be responsible for two other attacks in the same town, police said.
The 30-year-old woman, who was staying in Eastbourne, was assaulted in Hartfield Road at 10:15 BST on Sunday.
She suffered minor cuts and bruises after struggling with the man, and was left "very shaken and upset".
The man ran off after the attack, which may be linked with two sex assaults in two days last month.
In the first, on 26 August, a 48-year-old woman was assaulted as she was walking into Mountney Road from Green Street. The man ran off when she screamed and she was unhurt.
The previous day an 81-year-old woman was assaulted in Ditton Road. She was also unhurt.
"Although no serious injury was caused in any of these incidents they are of great concern to us," said Insp Rachel Barrow.
"Whilst they are being investigated we are carrying out extra patrols in the areas concerned."
Police are appealing to anyone who saw the man in the Hartfield Road area, just off Upperton Road, on Sunday or who has any information about any of the incidents to come forward.
