A CCTV image has been released showing a suspect police want to talk to after a young woman had acid thrown at her on her own doorstep.
The victim, who is in her 20s, was rushed to hospital where she remains with potentially life-changing injuries.
The suspect has been described by witnesses as a black woman, around 5'6" tall and as carrying a blue rucksack and wearing a face visor.
The CCTV shows a woman entering a supermarket on Thursday afternoon, after the acid attack which happened in nearby Brighton, East Sussex.
The clip shows a woman wearing an orange hooded jumper, light blue jeans, white trainers and a visor.
Sussex Police are appealing for witnesses to the attack which occurred at 4.20pm on Thursday in the heart of the seaside resort.
Nick Dias, of the force, said: "Our officers continue to work tirelessly to identify the suspect in relation to this matter and ensure an arrest is made.
"We need your help in identifying the person in the footage, do you recognise them?
"We believe the suspect fled towards Princes Street, Brighton, and then towards the seafront. We are urging anyone who witnessed someone acting suspiciously in this area between the hours of 3pm and 5pm on Thursday (20 May) to make contact with us.
"Patrols continue to be stepped up in the city, please do come and talk to one of us if you have any information or concerns."
