The brash pharmaceutical executive serving seven years in a low-security federal prison in New Jersey after raising the price of a drug 5,000 percent is running his business from prison using a cell phone smuggled into the facility, according to a report.

Martin Shkreli, who is housed in a 12-man cell at Federal Correctional Institution, Fort Dix is still heavily involved in Phoenixus, his private Swiss drug company, WSJ.com reported. The FBI is aware of Shkreli’s activities and is investigating the so-called “pharma bro” and his associates.

Until recently Shkreli was posting missives on Twitter from the phone. He even fired his CEO - who was on a safari in Africa- over the phone, the report said.

The 35-year-old was sentenced to seven years in prison for securities fraud.

Shkreli was jailed in September 2017 in a bizarre stunt when he offered $5,000 for a strand of Hillary Clinton’s hair while he was free on bail.

Before his legal woes, Shkreli stirred widespread rage when he boosted the price of Daraprim by more than 5,000 percent. Shkreli has become the public face of the pricing controversy, after his company jacked up the price after obtaining rights to the drug. The drug is the only U.S.-approved treatment for a deadly parasitic infection called toxoplasmosis.

The prison at Fort Dix features a range of gym equipment, racquetball courts, horseshoe pits, volleyball, bocce ball lanes, intramural sports, a music room, pool tables as well as hobby crafts. There are no bars, towers or locks on rooms within the community units.
