A 'despicable' Tajikistani national who attempted to rape a girl on a train has been jailed for 12 years and could be deported.Abdulmanon Aliev, 50, sat down opposite the 13-year-old on a train from Southend to London on the afternoon of June 16 last year and tried to use a translator app to speak to her.She moved away but he followed her and sat in an aisle seat to block her in, taking off his shorts and pants before attacking her.He touched her chest, put his hand under her tights to penetrate her, then tried to orally rape her, Inner London Crown Court heard.Aliev continued until the train arrived at London Fenchurch Street where the girl escaped on to another train and reported him.Officers arrested Aliev 11 days later in Peckham before searching his home, seizing the clothes he had been wearing on the day of the assault and charging him the next day.Aliev, helped by a Tajik interpreter, denied assaulting the girl and said he only touched himself in front of her because he had a skin condition.He wept as he told jurors: 'I have a wife and six daughters. I swear to God I have never done this. I can't even listen to this. She looks like my daughter. I don't know where these allegations come from.' Abdulmanon Aliev was jailed for 12 years after trying to rape a 13-year-old girl on a train last year Aliev, pictured on a train platform, took his shorts and pants off before attacking the girlAliev was found guilty in April of attempted rape, two counts of assault by penetration and three counts of sexual assault.Alongside 12 years in jail he will be a registered sex offender for life and spend two years on licence because of the danger he poses to the public.Judge Matthew Boyle told Aliev: 'Notwithstanding her obviously young age and vulnerability you took advantage of the victim sexually on a number of occasions as the train made its way towards the capital.'You instigated sexual contact by touching the victim's leg and vaginal area over clothing.'He said 'matters escalated further' as he touched her intimately before a horrified passenger confronted him.'To his substantial credit he told you the victim was just a girl and that you should stop.'Aliev left the train briefly, but then boarded the train again when he was confident he wasn't being watched, and started assaulting the girl again.'None of the sexual activity described was undertaken with the consent of the victim,' said Judge Boyle.'You took advantage of a 13-year-old child travelling alone on public transport for your own sexual gratification in the most appalling fashion.'I am satisfied that I should make a finding of dangerousness. That is to say that there is a significant risk of you committing further specific offences in the future and that those offences, if committed, would cause significant harm to others.' Aliev was filmed by CCTV crouching on a train, seemingly ducking out of view, after the assault The 'despicable' Tajik national, who 'took advantage' of the young girl, now faces the threat of deportation He was arrested 11 days after the attack by plain clothes police officers and found guilty of attempted rape in AprilDan Pawson-Pounds KC, prosecuting, said that Aliev also faced deportation.'He has been in the country since 2022. He is a Tajik national and he has applied for asylum unsuccessfully. I am told that deportation proceedings are ongoing.'The jury must have been sure that the victim did not consent to the conduct of Mr Aliev and that he did not have a reasonable belief in consent.'The victim was particularly vulnerable due to her age and isolation on the train.'British Transport Police had trawled hours of CCTV footage to track Aliev before and after the attack.Plain clothes officers spotted him near his Peckham home on June 27 and arrested him.Detective Constable Elizabeth Cahill, of British Transport Police, said: 'Aliev singled out a vulnerable child and subjected her to one of the most abhorrent sexual assaults I've ever investigated.'While the focus of attention will rightly be on him as the despicable sexual predator that he is, I want to pay tribute to the brave victim who reported him to police.'This verdict would not have been possible without her account of what happened and her willingness to support our investigation.'We take every sexual offence report extremely seriously, and we'll stop at nothing to put offenders like Aliev before the courts.'
