The Mumbai police are exploring legal options to prosecute Jagpalpreeth Singh, the prime accused in a murder case, after Belgian authorities denied permission for his extradition to India.

“We have been in constant touch with Interpol and Belgian authorities. We had issued a red corner notice and received a response stating that Jagpalpreeth Singh cannot be extradited to India as he is a Belgian citizen. They have informed us that he remains in Belgian custody,” said a senior police official on the condition of anonymity.
