The mother injured when she was doused with a corrosive liquid in south London had been in a relationship with her suspected attacker, police have revealed.

Investigators said the breakdown of the relationship may have been a motive for the harrowing attack, which saw the 31-year-old and her two daughters, aged three and eight, hurt.

A massive manhunt is underway for suspect Abdul Ezedi, with the last confirmed sighting now at around 11pm on Wednesday January 31, a few hours after the attack.

He was initially travelling around on the Tube network using his bank card and, after that, appears to have been walking a route that broadly hugged the River Thames.

The woman hurt in the attack, who may lose the sight in her right eye, remains sedated in hospital and is still too ill to speak to police.

Investigators said that she had agreed to meet him on the day of the attack, and that she and her children were in a car with Ezedi when he struck.

Commander Jon Savell, from the Metropolitan Police, said the breakdown of the relationship could be a motive for the attack last week.

Police have warned that the facial injuries suffered by Abdul Ezedi in the attack could be fatal if left untreated.

Police have offered a £20,000 reward to anyone with information leading to the 35-year-old’s arrest after they released more CCTV of him as they piece together his movements.

Ezedi, believed to be from Afghanistan, is understood to have arrived in the UK in 2016, reportedly in the back of a lorry.

He was handed a suspended sentence at Newcastle Crown Court on January 9, 2018 after pleading guilty to charges of sexual assault and exposure and was placed on the sex offender register for 10 years and ordered to carry out 200 hours of unpaid work.

Ezedi was accused of grabbing the bottom of a woman without her consent in 2017, as well as committing a sex act that same year, according to documents detailing the indictment which were disclosed by the court to the PA news agency on Tuesday.

Anyone with information is asked to the 24/7 hotline on 020 7175 2784 or for an immediate sighting dial 999.
