Police are investigating an alleged assault at a school after pupils were pulled from lessons and put into "emotional wellbeing" activities. 

A spokesperson for the Metropolitan Police has confirmed they have been made aware of an allegation of assault at a school in Bell Lane. 

It comes after a copy of a letter addressed to parents whose children attend Ark John Keats Academy in Bell Lane was shared online. 

The letter was signed by Ms E Penzer, the headteacher of the primary school key stages, making parents aware of an incident "involving a pupil" on October 24.

Ms Penzer wrote: "Today Shackleton class was taken off timetable and engaged with mindfulness activities to support their emotional wellbeing. 

"Senior leaders have been checking on the students throughout the day. 

"Further pastoral care is being put in place for the whole class to ensure every child feels safe and supported. 

"If your child chooses to talk to you about the incident, please encourage them to share their feelings with you as this will help them to process what happened."

The Met has confirmed there have been no arrests and that enquiries are ongoing. 

Parents were told in the letter that the school is "taking the matter very seriously and will act swiftly, in line with our staff and student behaviour policies". 

Ark John Keats Academy was contacted for a comment in response to the letter.
