Jaipur, Jul 12 (IANS): Police in Rajasthan's Churu district were questioning a man suspected of Reliance Jio data leak.

"We are questioning Imran Chimpa in the case. He belongs to Sujangarh in Churu. As the case has been registered in Mumbai, we are waiting for the investigators from Mumbai police to arrive and take over the investigations," a senior police official from Churu told IANS on phone.

Imran was brought to police station on Tuesday evening, official said.

Sources in the police said that Mumbai police was expected to arrive later.

A website, titled magicapk.com, claimed late on Sunday it has hacked into Jio database and has made personal details of its over 100 million users available on the website but Jio refuted reports of a breach into its database.

"We have come across the unverified and unsubstantiated claims of the website and are investigating it. Prima facie, the data appears to be unauthentic," a Jio spokesperson said in a statement.

"We want to assure our subscribers that their data is safe and maintained with highest security. Data is only shared with authorities as per their requirement," the spokesperson added.

The account of the website now stands suspended.

The domain name appeared to be registered somewhere in India. Various IP tracking websites track the geographic location of magicapk.com to Maharashtra.
