Shocked members of the public were disgusted to see a man and a woman engaged in sexual activity outside Newcastle Central Station.
It was on a Sunday evening that Kerry Walker was spotted carrying out a sex act on Lee Martin for three minutes at the taxi rank of the station.
One member of the public who witnessed it approached a member of staff at the station and told them it was "disgusting" and asked them to do something about it.

Just over half an hour later the pair assaulted a homeless man outside the station after demanding money people had donated to him.
Newcastle Crown Court heard the outraging public decency offence happened at 6.35pm on May 16 last year.
Glenn Gatland, prosecuting, said: "Kerry Walker was on the ground on her knees with her face in Martin's crotch area.
"It went on for around three minutes while members of the public and staff were in the area."
Just over half an hour later, the pair attacked the homeless man who had dozed off, again in front of members of the public.
He was woken by the pair, with Martin threatening him, asking for money and shouting and swearing.
Walker then picked up some of the victim's bags and hit him in the face with her hand before Marin punched him three or four times. He was left with a cut to his eye.
Martin, 40, of Tumulus Avenue, Walker, Newcastle, and Walker, 33, of Rectory Road, Gateshead, both admitted outraging public decency and assault occasioning actual bodily harm.
Martin also admitted burgling Boots in Newcastle city centre in October 2020 when he smashed a window with a pick axe and stole make-up worth £660.
Martin, who has 70 previous convictions, was jailed for five months, reduced to take into account the time he has served on remand while waiting for the case to conclude.
Walker, who has 164 previous convictions, who has been remanded in custody for 292 days, was sentenced to a community order with an eight week curfew.
Fiona Lamb, for Martin, said he was under the influence of drugs at the time of the offending and has a long-standing addiction.
She added that he is remorseful and had the opportunity to work for his dad's roofing business.
Rachel Hedworth, for Walker, said: "She is an extremely vulnerable individual who was spending a lot of time around Central Station.
"There is a background of mental health issues.
"She's utterly remorseful and extremely embarrassed.
"She has taken steps to address various addictions which have blighted her life since childhood."
