Delhi Teen Murder: The teen was stabbed repeatedly and then crushed with a rock slab by Sahil

New Delhi:

A 20-year-old man, who brutally murdered his alleged girlfriend in Delhi on Sunday, has been sent to the police custody for two days.

The teen girl was stabbed 22 times by Sahil, and then crushed with a rock slab in a busy street of northwest Delhi's Shahbad Dairy area on Sunday evening.

A new security camera footage, which is now going viral on social media, shows Sahil talking to a friend right before he killed the teen girl. 

In the video, Sahil is seen talking to Akash at the same spot where he later killed the teen.

Sahil speaks to Akash for about a moment before the man walks away, the video shows. Sahil appeared to be waiting there for the teen girl, officials said.

The girl was on her way to the birthday party of her friend's son when she was attacked, the police said.

A disturbing security footage shows Sahil stabbing the teen repeatedly, as people pass them by. Then he picked up a stone slab and struck her repeatedly, the chilling video shows.

The police, alerted by residents, arrived at the spot to find the girl's body and blood pooled around her.

Police said the girl had 34 wounds on her body.

"They were in a relationship, but they had a quarrel on Sunday. The teen was planning to attend her friend's son's birthday. The man followed her and stabbed her multiple times and hit her with a stone," a senior official said.

The killer, an AC technician, was arrested from Uttar Pradesh's Bulandshahr yesterday,

Sahil has confessed to the murder and claimed that he was upset because his girlfriend of three years wanted to break up with him.

During his interrogation, he allegedly told police that the girl was involved with a former boyfriend and that he has no regrets.

"He said he was enraged as the girl had been ignoring him for some time," police sources said.

The girl had even threatened him that she would go to the police, they added.

Sahil had been staying with his parents and three sisters at a rented house in Shahbad Dairy area for the last two years.

After the incident, Sahil switched off his phone and went to his aunt's home in Bulandshahr.

Sources say a call made by his aunt to his father helped police trace his location.

Delhi Chief Minister Arvind Kejriwal urged Lieutenant Governor V K Saxena to take strict action over the murder of the minor girl and said it was his responsibility to maintain law and order in the city.

Mr Kejriwal has announced a compensation of Rs 10 lakh for the girl's family.
