Bomb fears kept pupils indoors at Middlesbrough school
Pupils and residents were told to stay indoors when what was thought to be a grenade was found in Middlesbrough.
The device was discovered on Tuesday morning on grass outside the grounds of Hemlington Hall Primary School.
Headteacher Karen Edmenson was in touch with police and was advised there was no risk but children stayed inside and texts were sent to parents.
Bomb disposal experts from Catterick took the device away for further examination.
Mrs Edmenson stressed there was no danger to anyone and if there had been any risk, the school's 333 pupils would have been evacuated.
She said some parents living near the school had telephoned to check what was going on and the text message system had been used to keep them informed.
