Geneva Alert: Police Hunt Four Terror Suspects

Guards with MP5 sub-machine guns have been stationed at the entry points to the United Nations complex in Geneva as the search continues, Reuters reports.

Despite earlier reports, Swiss federal police said they have no information linking suspects to the deadly attacks in Paris last month in which 130 people were killed.

Swiss federal authorities tipped-off the officers, and the department of security said: "The Geneva police, on the basis of this information, have increased their level of vigilance and reinforced the number of police agents on the ground."

Geneva is more than 250 miles southeast of Paris. Police in Belgium and elsewhere have been searching for Salah Abdeslam, who rented a car which was used to carry gunmen to the Bataclan theatre in Paris, since the attacks.

The Brussels-based suspect - the brother of one of the suicide bombers - is thought to have fled Paris on the night of the massacres. 

The third gunman involved in the attack on the music hall has been identified as a 23-year-old man from Strasbourg.

Foued Mohamed Aggad went to Syria with his brother and a group of friends at the end of 2013.

Most of the others were arrested in spring last year when they returned to France, however Aggad stayed in Syria.

The attackers all died at the scene. Two had already been identified as Omar Ismail Mostefai, 29, and 28-year-old Samy Amimour.

Earlier this week members of the US band Eagles Of Death Metal broke down in tears as they returned to the Bataclan theatrefor the first time since the attacks.

They laid flowers and read cards at the site, where 90 people were killed when extremists stormed the venue as the band performed last month.

Where Is The UK's Terror-Arrest Capital?

Sky News-acquired data reveals arrests occurred within 21 force areas.

In 2014, by far the largest number of terror arrests were within the Metropolitan police area. The second largest cluster was in the West Midlands, followed by Greater Manchester and then West Yorkshire.

Interestingly, a year later, although the largest number of arrests were still within the Met police area, there is a noticeable shift to fewer arrests in the capital and more arrests in the West Midlands and Greater Manchester.

It is not always possible to get exact geographical locations for those arrested for terror offences, but the 195 we were able to trace over the last 18 months have been characterised by some distinct clusters in certain towns and cities.

London accounted for 80 arrests, about 40% of the total number detained under the Terrorism Act.

There were also significant clusters in Birmingham, 24, and Manchester, 12.

Some less obvious population centres - Rochdale, Cardiff, Luton, Derby and Portsmouth - also showed distinct clusters of terror arrests, most linked to individuals from those areas who either travelled to, or tried to travel to, Syria.

The number of women arrested on suspicion of terror offences has shown a statistically significant increase this year, compared with the year before.

In 2014, Home Office figures show 30 of 289 arrests were female - 10% of the total number detained.

Data up until the end of October this year shows 24 of the 104 arrests Sky News researched were female - 23% of the total.

That figure is expected to rise further when official figures and arrests for the last quarter of 2015 are included.

Again, the conflict in Syria and Iraq is seen as a driver for this increase.

Some high-profile cases, like the group of East London schoolgirls who travelled to Syria and others where women took their young children into that war zone, have also served to raise public awareness around female involvement in Islamist extremism.

Further analysis of those arrested under the Terrorism Act shows most, around two-thirds, are not subsequently charged with terrorism.

Although there were 289 terror-related arrests in 2014, only 102 were charged with a terrorism-related offence, just 35% of total arrests.

The arrest-to-charge ratio for terrorism offences is substantially lower in comparison to the charge rate for all criminal offences, at 58%

There is also a discernible trend showing younger and older people are being arrested for different types of offences.

The data shows those under 25 are more likely to be accused of active participation in terrorist activities, rather than encouraging or assisting others.

But that trend is reversed for those over 25, where far more are arrested for assisting or encouraging others, rather than active participation in terror activities.
