Police have detained 12 Yemenis who had previously been deported from the Kingdom but returned to join criminal gangs, while numerous others have been held on suspicion of a number of thefts. The 12 Yemeni men were using an old house in the south of the city as the hide-out from where they carried out petty thefts and pickpocketing and other illegal activities. Police had the site under surveillance and witnessed large number of workers frequenting the house late at night before raiding the location. Officers were forced to call for backup to deal with the number of individuals at the location, which totaled 35.
