The headteacher of a school where a machete wielding gang crashed a birthday party and stabbed two teenagers has spoken out for the first time.
Victoria Morris, the head of Elm Park Primary School in Havering, east London, said she was ‘shocked’ after more than 50 youths entered the building during a 16th birthday party.
Footage shows members of the gang brandishing knives and other weapons as party-goers run from the violence.
A 19-year-old and a boy aged 16 were taken to hospital with non-life threatening injuries.
The Metropolitan Police said its officers were also among those attacked, but they did not need hospital treatment after being seen by ambulance crews.

Speaking about the attack for the first time, Ms Morris said: ‘We were shocked to hear of a disturbance at a private birthday party in our hall over the weekend. This was a private hire and the people involved were not known to us.
‘No one was injured on the school premises and we have carried out thorough checks to ensure that pupils could safely return to school this morning.
‘We have successfully let our premises to the local community for years and have stringent protocols in place.

‘We have written to local residents and parents to give them our assurances of this and we have also decided that the hall will no longer be let out for evening events.
‘The incident is currently a police matter and we are helping with their enquiries.’
The Metropolitan Police said: ‘Police were called shortly after 9pm on Saturday March 22 to reports of a fight involving a group on Calbourne Avenue.
