BOMB threats have been made to six schools - with the lastest named as Four Dwellings Upper School, in Quinton, but police intelligence experts insist there is no credible threat.

Calls were made in quick succession at around 9am to Oldbury Academy, Bristnall Hall Academy, The Earls High School, Halesowen, Four Dweellings Upper School, Holly Lodge High School, Smethwick, and George Salter High School, West Bromwich.

It follows similar phone threats to Oldbury Academy, Bristnall Hall Academy, Leasowes High School, Halesowen, and Holly Lodge High School last week that saw thousands of pupils evacuated before police confirmed they were hoaxes.

Assistant Chief Constable Carl Foulkes, said: "Police intelligence suggests there is no credible threat behind the calls - they mirror the hoaxes several schools received just a few days ago.

"Local police officers have been sent to the affected schools to carry our checks and to offer reassurance.

"A police investigation is under way to find the person responsible for the calls."

Councillor Ian Cooper, cabinet member for Dudley children’s services, said: “Earls High school in Halesowen was evacuated after a bomb threat phone call this morning. Police are investigating the call but say there is 'no credible threat'.

“We are working with West Midlands Police on this incident but would like to reassure parents that the situation was dealt with quickly and safely and there are no suggestions of any threat to any other schools in the Dudley borough.”

A parent of a year nine pupil at The Earls said his daughter had texted to say they were being sent home, but this has not been confirmed.

The dad, who did not want to be named, slammed the school for failing to inform parents about what was happening and said they could have texted them.

Anyone with information which may aid officers find the caller should call police on 101.
