Gardaí have launched a renewed appeal for information on a violent sexual assault that happened in west Dublin last July.

On Thursday July 28th 2016, a young woman was walking with her bicycle at around 3.05am on the Lucan Newlands Road in Clondalkin in the direction of the Fonthill Road.

She was attacked and dragged into a secluded area where she was subjected to a violent sexual assault.

There were three men involved in the attack, and the incident lasted up to 15 minutes.

Gardaí say it is likely that the men involved were in the area for some time beforehand.

Crimestoppers and the gardaí are keen to hear from anyone who was in the area between 1.00am and 3.30am on July 28th 2016.

They also want to hear from individuals who may have any information in relation to the incident.

Calls to Crimestoppers, on 1800-25-00-25, are completely anonymous and callers do not need to leave their name or address.

Detective Inspector Mark O'Neill said: "We are appealing to the public to come forward with any information on who they saw in the area around Lucan Newlands Road in the early morning of Thursday 28th July 2016.

"Did anyone see the three males or see any suspicious activity in the area on that night?

"The local community was very helpful to our investigation when this crime was first reported.

"We are now asking people to come forward with any information at all they have.

"Even the smallest piece of information, which may seem insignificant, might help with the investigation.

"It is important for the safety of the community that we identify and bring these individuals to justice."
