RIYADH- Saudi security officers on Tuesday raided several illegal telephone operations here which were offering inter- national calls at cut-price rates. They were operated from small houses in the Batha and Al-Wazarat areas of the capital. “The raids on the illegal telephone cabins were carried out by the personnel of the Passports Department and led to the detention of 16 people’ * eyewitness Abdurahman Kutty told Arab News yesterday. Kutty said that a number of other expatriates involved in such operations were deported earlier. Over 120 illegal telephone cabins currently operate in Riyadh, employing some 1,000 expatriates.
