A gay man in London has been robbed and threatened with a cattle prod after meeting a man on the Grindr dating ad.
The 26-year-old man made contact with the other man and invited him to his flat in Bayswater, west London.
Upon arrival at the flat the man, described as blond and in his 20s, spent most of his time texting on his mobile phone before asking to leave.
When he was taken to the door an accomplice was waiting outside with a cattle prod. The pair pushed the victim back into his home where they threatened him with the cattle prod before taking cash and a laptop and leaving the flat in Queensborough Terrace.
The victim has not been named but was said not have received any serious injuries but to have been "very shaken" by the attack which happened on 28 September at about 5pm.
Police have issued CCTV pictures of the two men they are looking for and have warned that they may have targeted others.
Detective Constable April Smart, of Westminster CID, said: "Whilst we have not connected this incident to any other reported to us, I must consider that the suspects could have committed this type of offence previously and I would appeal to anyone who may have been a victim of this type of offence to contact the police, where they will be treated with the utmost sensitivity.
"I would like to take this opportunity to reassure the LGBT community that we are doing everything we can to arrest these men and have followed and eliminated a number of potential leads and inquiries to date.
"I would urge everyone who uses the services of online dating apps and sites to take steps to help them to stay safe whilst meeting strangers."
The first suspect is described as white, of slim build and in his mid-20s with short blond hair.
The second suspect is described as white, in his late 20s, of medium build and bald.
