Azan Majid Janjua was raped and murdered after being snatched from his mosque in Abu Dhabi while going for afternoon prayers during Ramadan two weeks ago.
His alleged killer posed as a woman to get Azan to the roof of a building because he knew the boy would not follow a man without talking to his parents, reported Gulf News.
CCTV shows the suspect carrying a handbag and walking into a lift with a young boy.
Police believe that the man is a Pakistani immigrant who took Azan to the roof of the apartment block where he then raped and strangled the schoolboy.
Major General Maktoum Al Sharifi from Abu Dhabi Police said: ‘He cross-dressed as a woman because he knew that the boy would not go with a man without permission from his parents.’
Azan’s half-naked body was discovered by air-conditioning technicians on May 31 on the rooftop of the building where he lived.
He had a copy of the Kuran beside him.
Azan’s father Dr Majid Janjua, 38, said: ‘He was fasting and he went to the mosque for Asr prayers and Quran recitation and then went missing.
‘I was shocked to know that AC technicians, who went to our building’s rooftop to check a malfunctioning chiller, found his body there around 10am. His body was half-naked.’
The suspect was arrested less than 48 hours after the body was found and detectives claim he has confessed.
Azan’s parents, who are from Russian and Pakistani decent, are believed to know the suspect.
