A 37-year-old man was arrested for attempting to kill the husband of a newly-married woman who was his love interest, the city police said on Friday.

Vivek Kumar Aggarwal, a resident of Budh Vihar in Rohini area, was arrested from his residence on Thursday night on a tip-off.

“On April 20, Aggarwal had fired at 28-year-old Piyush Malik while he was returning to his residence from a Metro station on a two-wheeler with his newly-wedded wife in Rohini Sector-5 area. Initially it appeared to be a blind case as no motive was found for the crime,” Deputy Commissioner of Police Rishi Pal said.

Malik, who works as a real estate consultant, picked up his wife daily from the Metro station in Rohini West. He suffered a gunshot wound on the back of his shoulder, the police said.

“Aggarwal was identified later after intense questioning of probable suspects and bad characters,” he added.

Aggarwal confessed that he was in love with the woman and hence wanted to kill her husband. He also attempted to kill Malik in February and was following him since then, waiting for the right opportunity to cary out the task.

Since he had no previous criminal background, Aggarwal changed his residence to deflect suspicion and avoid possible arrest.

“When he was listed as a probable suspect in the case, he tried to commit suicide by consuming sleeping pills,” the DCP said.

“Aggarwal also worked as a real estate agent. He had seen Malik’s wife in 2012 in Kirti Nagar area, where she was working with a real estate company. He fell in love with her and was dreaming of marrying her. After getting her number, he used to call her and send messages on Whatsapp,” DCP Rishi Pal added.

Aggarwal shot Malik as he was inspired by Shah Rukh Khan’s character in the Bollywood film “Darr”, the officer said, adding that he wanted to ruin the couple’s life after they got married in December last year.

“He also got a letter delivered to the parental house of woman to mislead the police investigation. In the letter, he accused Malik of destroying the life of girl by making her pregnant,” he said.
