Detectives in Derry are appealing for witnesses following the report of a serious assault in the Waterside area of the city in the early hours of this morning.
Shortly before 1:40am police received a report from a member of the public that a number of men were seen walking along Bonds Street armed with what was described as a sledgehammer and hammers.
Paramedics responded minutes later and discovered three men, two in their 30s and one in his 40s with injuries sustained as a result of what appears to have been a violent attack.
All three men were taken to hospital where they were treated for their injuries, which are not believed to be life threatening at this time.
Police believe the three men were the victims of an unprovoked and cowardly attack by four assailants armed with weapons.
They are exploring a potential link to loyalist paramilitaries as part of enquires.
Police are working to establish how the men sustained their injuries, who was responsible, what the circumstances were leading up to the incident and we are making a number of appeals.
They are keen to hear from anyone who was socialising in licensed premises on the Dungiven Road last night, and who witnessed any type of altercation.
Anyone with information is asked to contact detectives at Strand Road on the non emergency number 101.
