Officers have offered a £20,000 reward for information leading to Abdul Ezzedi’s arrest.
Abdul Ezzedi is wanted in connection with an attack in Clapham that left a woman seriously injured.
Investigators believe there is someone else who knows his whereabouts but has not come forward. They warned that anyone who helped him could be arrested.
A major police investigation continues, led by the Metropolitan Police, with dozens of officers working alongside other officers to find him.
Abdul Ezedi is still on the run.

Darius Nasimi of the Afghanistan and Central Asia Association appealed directly to Abdul Ezzedi, saying: “Mr. Abdul, I am speaking directly to you. I want you to go to the police station immediately.
“You are seriously injured and need medical attention, but more importantly, you must do the right thing and surrender to the police. You have been in this condition long enough.
“If you wish, please contact the charity and we will speak to you and work with you to assist the police with their investigation.
“Abdul, please contact us as soon as possible, call 999 or go to the police station.”
