Two victims of homophobic abuse on a train have said the police caution the perpetrator received as punishment is "too lenient".
British Transport Police confirmed a man, 56, was cautioned after reports of a homophobic-related incident on the Blackpool to Manchester Airport train.
The abuse was directed at Tyrone Ruscoe, 22, of Levenshulme and Alex Platt, 26, from Stretford, on Sunday.
The incident was filmed and posted on YouTube and has had almost 40,000 hits.
The couple were returning from a day out in Blackpool when it happened.
Mr Platt said: "We are disappointed he only received a caution and we posted the video on YouTube to raise awareness for homophobic abuse.
"It should be treated on a par with racial abuse."
Supt Pete Mason of the British Transport Police (BTP) said officers arrested the man on suspicion of a public order offence at Manchester Piccadilly station.
"Following an investigation he received an official police caution for a public order offence and was released from police custody the following afternoon."
He said "in light of additional evidence" he had instructed a review of the incident.
"I have asked our officers to review all the available evidence and the subsequent outcome."
He added: "Homophobic hate crime is very rare on the North West's rail network, but when it does happen it can be harrowing for those subjected to abuse and to those who witness it."
