UK police believe there may be further victims of a suspected rapist and murderer allegedly targetting victims on gay dating app Grindr. Adrian Murphy, who was originally from Kilkenny, was found dead at a block of flats in Battersea, south-west London, on June 4.

A post mortem examination failed to determine a cause of death, police are appealing for information surrounding the circumstances.

Officers conducting an investigation believe Mr Murphy was lured to the flat after chatting with a user on Grindr.

A 24 year-old man and a teenage girl were arrested in connection with the death of Mr Murphy on Wednesday, June 12, which police say is linked to an earlier alleged rape at an address in Walthamstow, north-east London, on May 30.

The 24 year-old was arrested on suspicion of murder, rape and theft and has since been bailed to attend a police station at a later date.

The 17 year-old girl, was also arrested on June 12 on suspicion of murder and theft, has since been released under investigation.

In the earlier incident, a 40 year-old man was allegedly drugged by a man he met on a social networking site and invited to his flat. He was found later that day by a friend and taken to a nearby hospital. He has since been discharged.

London Metropolitan Police have said property including laptops, mobile phones and cash were stolen.

Police now fear that there may be more victims and have issued a warning to users of Grindr.

Detective Chief Inspector Rob Pack, from the London Metropolitan Police’s Homicide and Major Crime Command, said: “We have linked these two incidents through our suspects and our inquiries continue to establish the exact circumstances.

“We know the victim in the Walthamstow incident met the male suspect through a social networking site and we are investigating whether there is a similar connection in Mr Murphy’s death.

“Both incidents happened over a short period of time and thorough inquiries have led us to make these prompt arrests. However, there is a possibility other offences may have been committed before May 30.

“Has anything similar happened to you, or someone you know? A meeting arranged online that has led to intoxication, robbery and possibly sexual assault? Please have the confidence to approach my team so we can investigate what happened to you. You can also contact third-party organisations such as the charity Galop. You will be taken seriously and treated with sensitivity.”

Mr Murphy was a seven-time All-Ireland Irish dancing champion and produced and choreographed shows like ‘Celtic Dance Force’, ‘Feet of Fire’ and ‘FireDance The Show’.
