DETECTIVES investigating the murder of an Edmonton schoolboy in April arrested two more suspects this morning, after two arrests yesterday.

Negus McClean, 15, was stabbed to death in Westminster Road on April 10 after stepping in to stop his younger brother's phone being stolen.

Police arrested two men, aged 25 and 18, this morning, in connection with his death, and both are now in custody at a north London police station.

Yesterday, police arrested an 18-year-old man and a 19-year-old man, who were bailed last night.

Detectives arrested 12 other people aged between 16 and 20 in the months following the death of the Edmonton County School pupil, and all have had their bail extended to later this month.

Police believe the aspiring rapper was chased by seven young black men on bicycles before being stabbed to death in front of his 13-year-old brother.

His mother Ingrid has made an emotional video appeal for information, saying: “I have no words to express how it feels to hear your son is dead. Negus died 16 days before his 16th birthday.

“He had his whole life ahead of him, there were so many things he wanted to do. He had so many plans and he will never do them now.

“He was always my baby. He was my Negus and that's what I called him. He was my perfect baby. He is missed so much.”

One of the suspects is believed to have been wearing a dark-coloured, possibly black, hooded jumper with a large 'Franklin and Marshall' logo on the front.

Detective Chief Inspector Stephen Clayman, of the Met's Homicide and Serious Crime Command, said: “I would urge anyone with information about the murder of Negus McClean to come forward and speak to my team.

“Others are now speaking to the police, so you will not be alone. Officers can meet you discreetly and out of your area. Your information will be treated in the strictest of confidence.”

Police are offering a £20,000 reward for information leading to the arrest and prosecution of those responsible for killing Negus – anyone with information should call the incident room on 0208 345 3775 or Crimestoppers anonymously on 0800 555 111.
