AMBERNATH: A 36-year-old man was arrested for allegedly killing his 10-year-old son for not attending school on early hours of Sunday.

After helping the police arrest her son for killing her grandson, the woman, Khatunbin Khan, 56, also died of cardiac arrest.

The accused, Aziz Majid Khan, a resident of Ambernath township in Thane district, last night questioned his son Sajid as to why he was neither studying nor attending school for several days.

When the boy could not give any satisfactory reply, Khan, in a fit of rage, beat him up severely with a stick on his head, following which he became unconscious, police said.

The police said when Khatunbin saw Aziz fleeing, she alerted the neighbours.

The neighbours rushed the boy to a local health unit for medical assistance. However, the boy succumbed to his injuries while being shifted to the Thane Civil Hospital.

“On Sunday morning, the police was informed by Khatunbin’s neighbour that she had suffered a cardiac arrest and died,” said Mahesh Chimte, assistant commissioner of police, Ambernath region of Thane police.

The accused has been booked under section 302 (murder) of the IPC and further investigations are on, police said.
