He BBC reports that Mehdi Rafsanjani, the son of Ayatollah Akbar Hashemi Rafsanjani, has returned to Iran aboard a flight from the UAE. He is expected to face charges for having a role in the post election disturbances in 2009, while presumably attending college (oxford) in Britain at the time.
It is probably no coincidence that Mehdi's sister was arrested and sent to Evin prison a day prior, to serve a 6 months sentence for anti-regime political activities. More to come in the coming days I'm sure.
Considering that most reformists would not survive the customary vetting process in the upcoming presidential elections in Iran, Rafsanjani senior is probably one of few semi-reformists immune to disqualifications as a candidate, given his status as one of the founding fathers of the Islamic republic. The regime maybe trying to dissuade him from running through the persecution of his children.
