Arup Patnaik admitted to Jaslok Hospital

"Patnaik was admitted after he complained about chest pain and doctors are attending to him," police sources said.

Patnaik had to vacate his post last week after he was promoted to Director-General rank and is now heading the Maharashtra State Security Corporation, while Satyapal Singh has been appointed as the new Mumbai police commissioner.

Sources said Patnaik is likely to be discharged after two or three days.
