Sister claims her husband killed Haryanvi singer Harshita Dahiya

However, Panipat police said they were examining the case from all angles and exuded confidence that they would soon crack it. A police official said Dinesh, the brother-in-law of Harshita Dahiya had threatened to kill her a few months back.

The 22-year-old singer was on Tuesday shot dead by unidentified youths at Chamara village in Haryana's Panipat district when she was returning home after performing at a function in the village.

On Wednesday when asked who could be behind the murder of Harshita Dahiya, her sister Lata said, "Dinesh, my husband."

"He got her (Harshita) killed because she was a witness in the murder case of her mother," she claimed while talking to reporters in Panipat on Wednesday.

Panipat DSP Desh Raj said, "Harshita's brother-in-law is charged with the murder of her mother. He is facing several criminal cases and is already in jail."

Dahiya's mother was killed in 2014 in Delhi and the singer was the prime witness in the case, the police said.

Harshita was living in Narela in Delhi.

Meanwhile, a video clip has emerged purportedly showing Dahiya claiming that she was being threatened by some artists from Haryana entertainment industry.

"Some people from our industry, our own artists from Haryana are threatening me over the phone to come to a compromise and delete the video, otherwise I will face consequences. I have not said anything wrong.

"Despite this, people are threatening me. I am not afraid of anybody. I will not delete our video... do whatever you want and I will not delete my live video. I am a Jaatni belonging to Jat community) and I am not afraid of death," Harshita was seen saying in the video.

It was not immediately clear which video she was referring to.

When asked about the video, the DSP said, "We are examining the case from all the angles. Several police teams are working on it and we will soon crack the case."
