A 14-year-old has been arrested over an acid attack which left a delivery driver “fighting for his life”.
The 32-year-old could lose his sight after a substance was repeatedly thrown in his face in Walthamstow on Thursday evening, police said.
In a separate attack in Tottenham about 30 minutes later, another delivery driver, also 32, had a corrosive substance thrown at him.
Police “strongly suspect” the attacks are linked, the BBC’s Danny Shaw said.
The home affairs correspondent added the victim in the first attack – during which two males tried to steal his moped – had injuries to his throat, face, oesophagus and eyes and was in an induced coma.
