A 14-year-old boy and 16-year-old girl have been arrested in the UK on suspicion of planning acts of terrorism.

The boy was held after officers from the North West Counter-Terrorism Unit and Lancashire Constabulary raided a house in Blackburn on Thursday.

Police examined a number of electronic devices found on the premises.

They suspect the boy of "preparing for an act of terrorism under Section 5 of the Terrorism Act 2006".

The girl was arrested after police and counter-terrorism officers raided a house in Clee Avenue, Longsight, Manchester, the following night.

She is suspected of "engaging in conduct in preparation for acts of terrorism".

Both youngsters have been bailed until 28th of May.

An eyewitness told the Manchester Evening News that Clee Avenue was "full of terrorist police" when the girl was arrested at around 8pm on Friday.

The ongoing investigation is not thought to be related to the Rochdale family detained in Turkey for allegedly trying to cross into Syria.

The five adults and four children were arrested on Wednesday and are due to be deported back to Britain later.

Police have searched three properties in Rochdale and two in Heywood as part of the inquiry.
