UPDATE: Arrests after major anti terror operation in Hampshire

Police swooped on addresses across the county carrying out a number of arrests.

In total three men and three women are being held following the operation.

Details of those arrested have not been released but they are from Portsmouth, Farnborough and Greenwich.

They are being held following the operation by the South East Counter Terrorism Unit, Thames Valley Police said.

Two men, aged 23 and 26, from Portsmouth, and two women, aged 23 and 29, from Farnborough and Greenwich respectively, are being held on suspicion of the commission, preparation and instigation of acts of terrorism, police said.

A 57-year-old man from Portsmouth was arrested on suspicion of failing to disclose information about acts of terrorism, engaging in conduct in preparation of terrorist acts and arranging availability of money and property for use in terrorism.

A 48-year-old woman from Portsmouth was also detained on suspicion of failing to disclose information about acts of terrorism.

Police were today standing guard outside a terrace house in Hudson Road, Portsmouth, which has been targeted as part of the terror raids.

The door window was smashed and police tape surrounded the property, while officers arrived at the scene with large property bags.

The house was previously raided by terror police in April this year. It is understood to be the family home of Ifthekar Jaman, who was killed in Syria in December last year after travelling to the war-torn country to fight government troops.

Jaman had become known for his online advice and encouragement to fellow British Muslims seeking to go to Syria, including women whom he urged to marry men back from the front lines.

An elderly neighbour said: ''There are always people going in and out, young men. You don't know what's going on.

''The police have been here before. There were lots of them, all with their lights on and everything.'

Another neighbour, who did not want to be named, said: ''I was woken up this morning by the police running in and shouting.''

The South East Counter Terrorism Unit worked alongside officers from Hampshire Constabulary and the Metropolitan Police to carry out a number of search warrants this morning.

A Thames Valley Police spokesman said: ''Officers would like to reassure residents that the police activity today is in relation to conflicts overseas and is not linked to any immediate threat to local communities or anywhere else in the UK.''

The latest arrests come after five men were detained last week in a series of dawn raids in central and west London.

Counter-terror officers said they had disrupted what was believed to be the early stages of what could have turned into a ''significant plot''.

Two of the five men have since been released from custody, while the other three suspects remain in custody after a warrant of further detention was granted at a magistrates' court.

A search has taken place at a business address in west London and searches were taking place at a further four residential addresses in north west London last night, police added.

Tarik Hassane, who lives in North Kensington, and Rawan Kheder, who lives in Chelsea, have been named locally as two of the men arrested last Tuesday.

Anyone with information is asked to call police on 101 nor the anti-terrorist hotline on 0800 789 321.
