Guernsey Police are appealing for help in their investigations into two sexual assaults on women walking home alone in St Peter Port.
The two separate attacks happened in the early hours of Saturday mornings, two weeks apart in July.
Police have asked for anyone with information relating to either incident to contact them.
They also stressed the importance of people taking responsibility for getting home safely after a night out.
The first assault happened in Forest Lane, near the junction with Smith Street, at about 0230 BST on 17 July and the second in Cambridge Park, just off the road of the same name, at about 0215 BST on 31 July.
Police said there was no description of the male attacker from the first assault as it took place in darkness.
The suspect for the second assault, who was scared off by the intervention of a third party, was described as white, 5ft 5in tall, with blonde spiky hair about 1in long and wearing a white T-shirt and blue jeans.
Guernsey Police said neither victim was under the influence of alcohol, but added that anyone who drinks excessive amounts of alcohol and makes their way home in vulnerable circumstances puts themselves at greater risk.
Det Ch Insp Ruari Hardy said for those walking home the advice was: "Stay as part of a group or arrange transport home.
"If you are going to walk home you should use a busy thoroughfare and stay on roads and streets that are well lit.
"You should ensure you have access to a mobile phone and ensure that you are in a fit state to get home."
