A reward of up to £20,000 is being offered for information leading to the arrest of Clapham chemical attack suspect Abdul Ezedi as police release new information about his movements.

Investigators believe there are people who know where he is who have not come forward.

They warned anyone found “harbouring or assisting him” will be arrested.

Ezedi, 35, has been urged by police to hand himself in after going on the run following the attack involving a corrosive alkaline substance in Clapham, southwest London, on Wednesday 31 January.

Twelve people were injured, including a mother, 31, and her two daughters, aged three and eight. All three remain in hospital, with the mother’s injuries thought to be “life-changing”.

Ezedi and the mother were in a relationship, a relative of the suspect has told Sky News.

The Metropolitan Police said today that the last confirmed sighting of him is now at 9:33pm on the day of the attack, when he exited Tower Hill Underground station.

He had changed trains at Victoria, where he arrived on the Victoria Line at 9.10pm and departed on the eastbound District Line at 9.16pm.

The Met has said it is continuing to analyse CCTV footage alongside “many other lines of inquiry” as they attempt to locate Ezedi.

The force has said dozens of officers are working together to trace him.

Met Commander Jon Savell said: “I am hugely grateful to the public for the significant number of calls that we have received.

“Your help is critical. A reward of up to £20,000 is now available for information leading to his arrest.

“I must warn anyone who is helping Ezedi to evade capture – if you are harbouring or assisting him then you will be arrested.

“Our inquiry line is staffed 24/7 by specialist detectives who are progressing enquiries around-the-clock.

“If you know where he is or have information that may assist call them now.”
