Investigators will summon Janepob Veeraporn, a suspect in last month's deadly high-speed car crash in Ayutthaya that killed two postgraduate students, to answer further questions in the next week, police said.
Deputy chief of Ayutthaya provincial police Surin Tappanbussapa said investigators probing the crash told him that Mr Janepob, 37, had been discharged from a hospital where he received treatment for a knee injury following the accident.
On March 18, police took Mr Janepob to Ayutthaya Provincial Court to begin 12 days of detention. But his lawyer filed a request for bail on the grounds his client needed further treatment.
He left hospital on March 29. Investigators will order the suspect to answer questions by next week, Pol Col Surin said.
Mr Janepob was driving at high speed when he rammed his Mercedes-Benz into the rear of the Ford in which the post-graduate students were travelling on Phahon Yothin Road in Ayutthaya's Bang Pa-in district.
Police say the Mercedes was travelling at speeds of 215-257 kilometres an hour at the time of the collision. Thanthaphat Horsaengchai, 34, and Kritsana Thaworn, 32, were killed in the crash after their car was engulfed in flames.
Janepob: Charges include reckless driving causing death
Mr Janepob was charged with reckless driving causing death and property damage, drink-driving causing death and driving while unfit to do so. Police say anti-depressant medication which can make a patient drowsy was found in his car. Police also are set to file additional charges of speeding, and driving without regard for safety causing death.
Investigators will also write to Immigration Bureau chief Nathathorn Prousoontorn, asking him to seek a court order banning Mr Janepob from leaving the country, Pol Col Surin said. Police will interview the students' parents and Mr Janepob's father next week, he said, adding 90% of witnesses had completed their interviews.
