The accused, identified as Shahzad Ahmad, is a resident of Chilla Village near Mayur Vihar Extension and was in a relationship with the woman for around the past one and a half years, DCP (East) B S Gurjar said today.
Things turned bad when Ahmad found out that his girlfriend also had an intimate relationship with another man.
When he did not turn up, the e-rickshaw driver left the vehicle and started looking for him. Meanwhile, people in the area raised an alarm about a suspicious object on an abandoned vehicle. When a police constable inspected the bag, he found the body of the woman.
A case of murder was registered and a police team formed to crack the case. They zeroed in on the accused through local intelligence and technical surveillance, following which he was arrested yesterday, police added.
