Two others suspects for whom arrest warrants have been issued are still on the run.
The victim is Renu Tankanjananurak, executive of Burapasinsub real estate company, who is also the associate judge at the juvenile and family court.
The three suspects, who are also women, are said to be staff members at Renu’s company.
Renu was allegedly abducted and assaulted and her car was pushed into a river, apparently with the intent of drowning her. She was later found on the river bank and rescued.
She is currently in ICU under police custody for fear her attackers may return to kill her.
Police suspected that the motive behind the attack was related to a Bt200-million land deal.
