A 45-year-old construction worker from UP's Sultanpur district allegedly beat his wife to death after she failed to answer his phone calls throughout the day.
Kusum, 42, was declared dead by doctors after her children took her to the hospital, despite her daughter taking her to a relative's house in an attempt to escape the abuse.
The accused, Nakched, was arrested and during interrogation, admitted to assaulting his wife, but claimed he did not realise the attack would prove fatal.
The couple has two minor children and an elder son, who works in Punjab.
