Police said a list of 11 accused, including five officials of the orphanage, had been submitted before the Judicial First Class Magistrate court.
The case relates to UAE national Jasem Mohammed Abdul Karim Abdulahmed marrying the 17 year-old girl from the orphanage in June last. He left the country in July and divorced her through 'triple talaq' over phone.
Police said they were trying to extradite Jasem, who has been named the first accused in the case. The accused, son of a UAE-Malayali couple, who had resided in India for six years, later adopted the domicile of his father, police said.
Three persons have already been arrested in connection with the case--Sulaika, the mother of Jasem, her second husband C Muneer, and Abu Shahabaz.
The accused have been charged under various sections of IPC for Rape, Prohibition of Child Marriage Act, Juvenile Justice Act and Protection of Children from Sexual Offences Act.
Police took evidence from the girl, her family members from Malappuram and the orphanage authorities, who allegedly facilitated the marriage.
