Two men have been arrested in connection with an armed robbery at a school in Greater Manchester.
Police said a man armed with a spanner forced his way into St Richard's Primary School in Wigan, on Monday.
He stole cash from the reception area before grappling with the head teacher of the school and running off.
Two men, aged 18 and 22, were arrested on suspicion of robbery. The teenager was later released without charge and the man has been bailed.
Det Con Elaine Dickinson said: "How anyone could target a school is beyond me.
"This was a frightening attack that has left some staff understandably shaken. Fortunately the staff co-operated with the offender's demands and no one was injured.
"Security at the school is very good and I would like to reassure parents this type of crime is extremely rare."
