A teenage boy and girl have been arrested on suspicion of preparing acts for terrorism.

The 14-year-old boy was arrested in Blackburn, Lancashire, on Thursday, while the girl, 16, was arrested after police raided a house in Longsight, Manchester, on Friday.

They were both arrested as part of the same investigation on suspicion of terror-linked offences and have been bailed until May 28.

The investigation involves the North West Counter Terrorism Unit, Greater Manchester Police (GMP) and Lancashire Constabulary.

Police said on Thursday the examination of what they described as a "number of electronic devices" led them to execute the search warrant at the house in Blackburn.

The 14-year-old boy was arrested on suspicion of preparing for an act of terrorism under Section 5 of the Terrorism Act 2006.

The day after officers from GMP's Tactical Aid Unit and North West Counter Terrorism Unit executed a warrant at a house in Longsight, south Manchester.

The 16-year-old girl was arrested on suspicion of engaging in conduct in preparation for acts of terrorism.

The arrests come as nine individuals from Rochdale, Greater Manchester, are being held in Turkey after allegedly trying to cross the border into war-torn Syria.

It is not believed the arrests in the UK are linked to events in Turkey.
