Mohammed Ahmed Mohamed, Al-Shabab Terror Suspect, Wore Burka To Evade Surveillance

Police have lost track of a terror suspect in England after he entered a a mosque on Friday and left it wearing a burka, a garment worn by some Muslim women that covers the entire body, face and eyes.

Security camera footage shows the suspect, Mohammed Ahmed Mohamed, entering the An-Noor Mosque and Community Centre in west London on the morning of Nov. 1 and then changing into a burka.

According to the BBC, authorities believe the Somali-born 27-year-old was trained by and fought with al-Shabab, the Somali militant group that claimed responsibility for killing 68 people in the September terror attack on the Westgate Shopping Mall in Nairobi, Kenya.

Mohamed had been placed under a Terrorism Prevention and Investigation Measure, a type of government control order in England used to keep an eye on suspects who cannot be prosecuted or deported. He was also outfitted with a tracking device, though it is unclear whether he removed it, reports ABC News.

England's ports and borders are on the alert for the suspect, who had his passport confiscated previously and who security officials say does not pose a direct threat.

A recent poll found that the majority of U.K. residents want face veils banned in public, but a judge lent support to Muslim women's rights to wear a burka or niqab, the latter of which covers the entire face except for the eyes. The judge ruled that a 22-year-old Muslim woman accused of witness intimidation could keep her face covered while standing trial, as long as she removed it while giving evidence.
