Paris Valeta Bregazzi, 30, has pleaded guilty to one count of carrying out an unlawful act on a railway with intent to endanger a person

A transgender woman shoved an off-duty police officer onto a railway line after she downed four bottles of prosecco and took drugs during a wild night out, a court heard.

Paris Valeta Bregazzi, 30, barged PC Sam Chegwin onto the tracks at Hanger Lane Station in Ealing, west London, when he told her to 'calm down' after she became abusive and aggressive towards other passengers.

PC Chegwin 'mercifully' suffered only minor injuries after his head landed inches from the line which became live as the first train passed through seven minutes later.

He quickly climbed back onto the platform and arrested Bregazzi at 5.15am on July 17.

Bregazzi, who has recently had breast implants and cosmetic surgery worth £10,000, was detained in a male prison before pleading guilty to one count of carrying out an unlawful act on a railway with intent to endanger a person on November 21.

Judge Jeremy Dein, QC, released her on bail after telling the court he was 'concerned' she has been held in custody 'in very difficult circumstances'.

Judge Dein said he did not 'feel comfortable with imposing an immediate sentence of imprisonment' and deferred sentence until February.

The Old Bailey heard the offence carries a maximum sentence of life in prison.

Prosecutor Geoffrey Porter said: 'Ms Bregazzi came into the station with a friend. Also on the station were other passengers. It was early in the morning and they were awaiting the first train to pass through Hangers Lane that morning.

'Among the passengers was Mr Chegwin. Mr Chegwin is a police officer but was off duty and wearing civilian clothes.

'He was sat listening to music through his headphones and he could still hear an argument which seemed to be between Ms Bregazzi and her friend.

'The officer then noticed that Ms Bregazzi's behaviour became abusive and aggressive towards other passengers. At this point he decided that he had to become involved. He asked her to calm down and she was abusive to him.'

CCTV footage shows the moment Mr Chegwin confronted Bregazzi and pushed her away when she became abusive.

Mr Porter continued: 'The officer said that he pushed her because he was concerned to make a "safe space", as he puts it, between himself and Ms Bregazzi.

'At that point she then proceeded to push him hard across the platform and he went onto the lines. He landed on the rails.

'His head came within inches of coming into contact with the live line, though my understanding is that the line at the time wasn't live. It wouldn't have been until the train came.'

PC Chegwin quickly got back onto the platform and arrested Bregazzi before more officers attended and took her away from the scene.

Mustapha Hakme, defending Bregazzi, said she is one surgery away from fully transitioning to a woman and has been in custody at a male prison since July 17.

Mr Hakme said: 'There is no doubt that her mental health issues have been exacerbated by her being transgender and the transition she has made so far.'

The court heard Bregazzi had struggled to deal with her parents 'disowning her' after she came out aged 19.

'Their reaction shocked even her,' added Mr Hakme.

'She is someone who as a result has been left full of anger and at the same time sadness and is effectively heartbroken by the rejection she feels.

'This is a defendant who is desperate to complete her gender reassignment and just effectively get on with the rest of her life.

'While she's in that transition period there can be no doubt that it's making its toll emotionally as well.'

Bregazzi already has 40 convictions for assault, harassment and shoplifting designer frocks dating back to 2007, including attacks on staff and commuters at Highgate Station, East Finchley Station and Kings Cross Station.

Judge Dein described her record as 'appalling', but said he felt her attack on PC Chegwin was a 'low level' offence that could be dealt with by a suspended sentence.

He said: 'You appear to be in a heated exchange with your friend, ultimately a person involves himself. That person turned out to be an off duty police officer - you didn't know that.

'That person pushed you first. Whether that was necessary or not is in my view open to question.

'Your criminality amounts to you having responded by pushing that person, Mr Chegwin, and he ended up on the railway.

'I'm fully satisfied that you didn't intend to push him onto the railway line.

'It's open to question in my view whether you intended to endanger him at all, but you have pleaded guilty to that offence.'

Judge Dein told Bregazzi he would defer sentencing until the week of February 19.

Bregazzi, from Islington, north London, must attend probation appointments, drug misuse appointments, engage with her GP and medical services and live and sleep at her flat while she is on bail.
