A Greenwich woman is among six people being held on suspicion of Syria-related terrorism following police raids this morning.

Officers from the South East Counter Terrorism Unit, working alongside the Met Police, arrested the 29-year-old woman on suspicion of commission, preparation and instigation of acts of terrorism.

A 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."

Police also arrested a 23-year-old woman from Farnborough, Hampshire, and two Portsmouth men on suspicion of the same offence.

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 arrested for failing to disclose information about acts of terrorism.

Meanwhile, Gusai Abuzeid, a Greenwich student arrested in terror raids last week, has now been released without charge.

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.

He also made an appearance on BBC Newsnight.

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."

Anyone with information should contact police on the 101 number or the Anti-Terrorist Hotline 0800 789 321.
