According to a statement issued by the Bhavani Nagar police, along with the foreigners, the other accused included a Qazi (cleric) and the owner of a lodge.
The release claimed the Bahrain nationals targeted poor Muslim families of the city by offering huge cash and gold for "marriage".
"To perform marriages they would contact local brokers by giving them huge commission. After collecting commission from the Bahrain nationals, local brokers would arrange poor Muslims girls for performing marriage with them," police said.
The victims were sent to India without divorce and the foreigners would once again go on searching for girls from poor families for marriage, they added.
Both the Bahrain nationals are siblings, the statement said.
