ARMED police have raided two houses in Hampshire and arrested three suspected extremists under anti-terror laws.

They are being held under the Terrorism Act in connection with ''suspected domestic extremism'', police said.

Armed officers were used to detain a 25-year-old man outside a house in Crossways, Aldershot, Hampshire, yesterday afternoon. He is being quizzed by detectives.

A second house at nearby Denmark Square was cordoned off. A 26-year-old man and a 22-year-old woman were also arrested and are in custody, a Hampshire Police spokeswoman said.

The two properties will be searched by police over the next few days.

The spokeswoman would not give any more details of the incident or further explanation of the allegations.

''This is an ongoing investigation, led by Hampshire Constabulary's Serious and Organised Crime Unit,'' she said.
