Jermain Ogunbiyi, 26, from Hamilton View, Leeds, appeared at Leeds Crown Court on Tuesday (6 May) to be sentenced after pleading guilty to assault occasioning actual bodily harm (ABH) in relation to the attack, which took place in the early hours of Sunday, 6 April.
Ogunbiyi pleaded guilty to the attack on the woman, who was four months pregnant and known to Ogunbiyi, at an earlier hearing. He was also in breach of a suspended sentence for a previous assault on the same victim in 2013.
The court was told that, on the day of the attack, Ogunbiyi saw the woman in the Back Room bar celebrating her birthday and wished her a happy birthday.
A short while later he approached her again and grabbed her around the throat, causing severe bruising and scratches to her throat and chest as he did so.
At court on Tuesday he was sentenced to one year in prison for ABH and a further 18 months for breach of the suspended term, with both sentences to run consecutively. He was also made subject of a restraining order of indefinite length preventing him from making contact with his victim.
Detective Constable Jason Ridgway, who led the investigation for British Transport Police (BTP), said: â€œThis was a nasty and unprovoked attack, made worse by the fact that Ogunbiyi had previously been convicted for an assault on the same woman last year.
â€œThis assault has had a deeply damaging effect on the victim and I hope this conviction, and the fact that her attacker has fully admitted what he did, can bring her some solace.
â€œWe treat all reports of violent attacks with the utmost seriousness and will always do everything in our power to identify those responsible and bring them to justice.â€
