Anissia's father complained about in-laws last month

The family of a female flight attendant, who had reportedly committed suicide in south Delhi's Panchsheel Park, had submitted a complaint to the police last month stating if anything happened to her, "it should be treated as a case of murder".

According to a friend of Anissia Batra, who did not wish to be named, her father Major General Roopinder Singh Batra had submitted a letter on June 27 to Hauz Khas police station stating that Anissia's husband and his parents could harm her.

"They may physically harm her and show it as an accident or suicide. Kindly note that any harm to her will be directly attributable to plans made by my son-in-law and his parents (sic)," the letter stated.

Anissia' friend accused her husband Mayank Singhvi and his parents of deviating the case. Mayank was arrested on Monday on charges of dowry death.

"Mayank's parents had applied for an anticipatory bail seeking exemption till today (Friday). During the hearing on Friday, Mayank's lawyers tried to deviate the case by saying that he gifted her BMW and expensive stuff," the friend claimed.

Singhvi's parents were granted exemption from joining the probe by the court till Friday on personal grounds. The court hearing is currently underway.

Anissia's parents have claimed that her husband used to physically abuse her.
