Detectives hunting the Clapham attack suspect Abdul Ezedi believe he is either being harboured from capture or is dead, with no trace of him for more than 100 hours despite a massive manhunt. Police say there has been no sighting of him since last Wednesday evening, after he allegedly threw a corrosive substance at a woman – who is still sedated and may lose the sight in her right eye – and two young children aged three and eight. Hundreds of hours of CCTV has been examined with the last confirmed sighting being of Ezedi near Southwark Bridge at 9.47pm on Wednesday. The last use of a bank card by Ezedi, 35, was when he exited Tower Hill station at 9.33pm on Wednesday after travelling on the London underground network. His mobile phone has been found in the car left abandoned at the scene in Clapham, south London, and is being scoured for clues, including how the suspect and victim knew each other. The victim’s mobile phone has also been examined to understand why the attack happened, with police saying they have no “hard facts” as to a motive. Cmdr Jon Savell said of the search to find Ezedi: “We’ve got a number of hypotheses to talk in police terms about what might have happened. “Him having come to some harm is obviously one of them. I think that it’s realistic to understand that the fact that no one has seen him recently and he’s not been spotted by anybody would mean that he has either come to harm and is lying somewhere and yet to be found, or someone’s looking after him, as he’s not been outside for some time. I think they are the obvious two hypotheses.” Det Supt Rick Sewart, leading the manhunt, said it could take some time to find the suspect if he is hiding: “If we are in a situation whereby he is being held in one specific address it clearly could take several weeks, if he’s being fed and watered by somebody and wants to lay low.” Sewart said he was keeping an open mind on whether the attack was planned solely by Ezedi or not, and that there is no sign he was planning to go on the run or into hiding, saying: “It is our belief that someone in the community will know more about the whereabouts of Ezedi.” The 31-year-old woman left seriously injured is still too ill to speak to police, has been sedated since the attack, and left with “very significant facial injuries”. There is concern for the sight in her right eye and Savell said he cannot confirm whether the woman and suspect were in a relationship. One hundred specialist officers are part of the manhunt, which is staffed like a major murder hunt or counter-terrorism operation. Sewart said: “It’s always more difficult to crack a manhunt where they don’t have their mobile phone on them.” Police have worked through 200 calls of possible sightings, and asked anyone who thinks they have seen Ezedi – left with significant facial injuries after the attack – or knows something to call them, with a £20,000 reward on offer. Police said that early on Monday detectives arrested a man aged 22 for assisting an offender. He was released later the same afternoon on bail within hours of being detained, with inquiries continuing. Police said officers from the counter-terrorism fugitive team are helping sift through hundreds of hours of CCTV. The main focus is on London and Newcastle, where Ezedi lived. A search of his flat uncovered bottles of corrosive alkaline chemicals believed to be liquid sodium hydroxide or liquid sodium carbonate. Sewart said police were talking to neighbours and associates of Ezedi and he could be hiding in the north-east or the capital. Ezedi’s “key” link to London was that he was visiting the victim, police said.
