The accused in the killing of 23- year-old engineer Anjali Rathour has been arrested by Noida Police from Mainpuri in Uttar Pradesh.
Ashwini Yadav (24) was a college classmate of Anjali and claimed to have been in a relationship with her, police said.
After his arrest last evening, he confessed to the killing, they added.
Anjali was found dead at the parking lot of her residential complex, Shatabdi Vihar, in Noida on May 31. CCTV footage had shown a man chasing her with a pistol.
Yadav said he had killed her as she got into a relationship with another man and started ignoring him after he lost his job.
According to police, Yadav had met Anjali a day before the murder. He had bought a country-made pistol from his home town of Etawah and planned the killing with an accomplice.
The next morning he entered the society and called her to the parking lot. Sensing trouble, Anjali had tried to run, but was shot dead.
