There's a fine balance between causing unnecessary alarm and sharing information so that parents can judge risk.
In a weekly safeguarding update to schools this morning, serious youth violence was highlighted:
Unrelated information sharing between schools later today also highlighted a teacher at another school robbed of a mobile phone by a moped rider, while walking along the Little Ealing Lane area during a lunch break. The other school reported this robbery to local police.
Parents are encouraged to take steps to reduce own risk and keep safe from street crime, guiding own children accordingly.
