Indian diplomat Madhuri Gupta, arrested on charges of spying for Pakistan's spy agency ISI, had visited the Sunderbani border area in Jammu and Kashmir last month and stayed with a doctor couple, intelligence sources said.

Gupta, 53, had been to Sunderbani, close to the Line of Control (LoC) in Rajouri district, for two days on March 28 and 29 this year, intelligence sources said. Officials said they do not have exact information on the kind of relationship the diplomat had with the doctor couple.

"At some stage, it might be investigated," an intelligence official said.

Gupta, a second secretary with the Indian High Commission in Islamabad, has been remanded to police custody. The Indian government Tuesday said it was questioning Gupta for passing sensitive information to Pakistan.
