Women are being urged not to jog alone after a man dragged a young mother into the River Boyne and tried to strip her in an early morning attack.
The sinister attack happened at 9am last Thursday and gardai are concerned that the culprit could strike again.
The victim was jogging on her own when she was attacked on the footpath that runs alongside the Boyne and connects Drogheda with Oldbridge near the site of the Battle of the Boyne.
No arrests were made over the weekend but witnesses are being sought.
"There is no CCTV in the area and the attack happened while it was very foggy along the riverbank, but gardai are anxious to catch this man because you can't rule out that it wouldn't happen again," a source told the Herald.
"The attacker didn't speak a word during the attack, and his appearance is very non- descript, but gardai are hoping that somebody might have seen him after the attack because he would have been soaking wet," they added.
Gardai are now putting together a photo-fit of the suspect, and questionnaires are being handed out to people who live and work nearby.
The woman first noticed there was a man behind her as she jogged over the bridge of peace, in the town centre, and she then turned down to St Dominic's Park and made her way along the ramparts walkway to Oldbridge.
The attacker is described as being aged 23-25, of thin build and about 5 feet 7 inches tall.
He was wearing a black woolly hat and black jacket and had on either black trousers or jeans. The jacket he was wearing was too big for him, gardaí said.
The man is described as having a pale face and blue eyes.
Gardaí say the woman got out of the water after the man had fled and met another jogger who brought her to the garda station.
Anyone with information is asked to contact gardaí on 041-987200 or the Garda Confidential Line 1800-666-111.
