The court of chief judicial magistrate in Madaripur granted the remand, though police had sought 15 days to grill the suspect.
Three youths hacked Ripon Chakrabarty, a mathematics teacher at Madaripur’s Government Nazimuddin College, with sharp weapons on Wednesday afternoon in an attempt to kill him.
The assailants first knocked the door of the teacher’s home near the college’s main gate. As soon as he opened the door, they attacked him and tried to chop his head off, police said.
Fahim was caught by the locals who had rushed to Ripon’s help hearing his cries.
The injured teacher was first taken to Madaripur Sadar Hospital and then transferred to Barisal’s Sher-e-Bangla Medical College Hospital.
Sub-Inspector (SI) Ayub Ali filed a case in connection with the attack on Thursday night with Madaripur Sadar Police Station against six people.
