The school attended by a 15-year-old stabbed to death in Woolwich has warned students to avoid “flashpoints” in the town centre, according to reports.

Tamim Ian, 15, a Harris Academy Greenwich pupil, died at around 6pm on Monday night, after he was found suffering severe stab wounds on Woolwich New Road.

In a joint statement to parents seen by the Evening Standard, Harris Academy Greenwich executive principal George McMillan and Principal Ben Keely encouraged children to go directly home from school each day.

The statement reads: “We are shocked and devastated at this tragic and senseless loss of a child’s life.

This Is Local London:

"Our thoughts and prayers are with the victim‘s family and we will do everything we can to support them at his time.

“We are also supporting students very closely, particularly those who knew him well or were in his year group.

“We held special assemblies with the children, where we marked his life and ensured that students know that they can come to us if they need someone to talk to or help with managing their shock and grief.

“We also reiterated our frequent message about staying away from flashpoints in the area, which are Woolwich town centre and the local McDonalds.

“We ask parents to help us reinforce the message that our children should go directly home after school each day.”

Another 15-year-old who self-presented at a south London hospital with a non-life-threatening stab wound on Monday has been arrested on suspicion of murder.

Police were granted additional powers to disperse groups across the Greenwich borough over the last 24 hours.

Bouquets of flowers were laid down at the scene from early Tuesday afternoon onwards.

It is understood that the block of shops outside which the stabbing occurred is likely to be cordoned off for the next few days.
