A man has been arrested in connection with an acid attack on an aspiring model and her cousin.
John Tomlin was held on suspicion of grievous bodily harm with intent over the alleged attack in Beckton, east London, on 21 June.
The 24-year-old handed himself in at a police station and was being held in custody, Scotland Yard said.
Resham Khan and Jameel Muhktar, 37, were attacked by a man throwing acid through their car window on Ms Khan's 21st birthday.
Both suffered life-changing injuries in the attack that took place just after 9.10am on Tollgate Road.
In the days afterwards, Ms Khan said: "I'm devastated. I keep wondering if my life will ever be the same."
In a Facebook post, she stressed he did not want the incident to "fuel a division among people".
"There will always be a sick and twisted minority ... make peace with each other and the world," she said.
Mr Mukhtar has said he feels "emotionally wrecked" and "in continuous pain".
In an emotional interview with Channel 4 News, Mr Mukhtar described the feeling as "like somebody's ironing me 24/7".
Scotland Yard said their investigation into the incident was continuing.
