"We conducted a search operation and recovered three mobile phones from Gogi and his associates in Tihar. We have handed over the phones to police and they are conducting further enquiry in the matter," a senior jail official said.

The jail officials said they are also conducting an internal enquiry on how Gogi and his associates got access to cell phones.

The police said they are questioning Gogi and an investigation is underway to ascertain if the extortion call was made by Gogi or any of his associates from inside or outside the jail. An investigation is being conducted with the help of jail authorities and security has been provided to the victim.

Gogi, who carried a reward of Rs 4 lakh on his head announced by the Delhi Police and Rs 2.5 lakh by the Haryana Police, was arrested from Gurgoan in March this year and is lodged in Tihar.

He is involved in several cases of murder, attempt to murder and extortion among others.
