Police have reassured residents in the wake of a double stabbing in High Mead off Station Road on Wednesday.
Two 17-year-old boys were injured in the incident with police called to reports of an altercation in the road just before 5pm.
One of the young men was stabbed in the neck but later released from hospital. The other victim was stabbed in the leg and as of last night was in a critical but stable condition.
However, local police have stressed local people are not at risk. They are now working closely with the Trident gangs unit.
Sergeant Craig Hands from the Greenhill Safer Neighbourhood Team attended last night’s HCRA meeting to allay fears.
“I want to reassure residents that there is no increased risk to them as individuals,” he told the meeting.
He said police were confident they would swiftly get a “positive outcome” from the ongoing investigation.
Crime rates continue to fall in Greenhill ward and Harrow was still the safest borough in London, he added.
