A Muslim father in Germany has confessed to choking his 19-year old daughter to death while asleep after the teenager was apprehended by police for stealing condoms from a store, according to a German newspaper.

Asadullah Khan, 51, an immigrant from Pakistan, is facing trial together with his wife Shazia, 41, before a court in Darmstadt, Germany, for killing their daughter, Lareeb Khan, a dental technician, the German paper Bild said.

Khan told the court in the Sept. 25 hearing that he strangled his daughter to death after learning she was sexually active with her boyfriend and had previously resisted attempts to enter into an arranged marriage.

Khan claimed that the family's honour had been tainted after Lareeb started dating a man who he did not approve of, said Bild.

In her statement read out in court, Shazia said Lareeb had stayed away from the family for several nights in a row and had stopped wearing her headscarf.

She also told the court that her husband got mad after they received a letter from police informing them that Lareeb was arrested for stealing condoms.

"At this point it became clear that there was sexual contact. When I showed the letter to my husband, he snapped,'' the report said.

After Lareeb died of strangulation, the couple dressed their daughter in her dental assistant work attire and used a wheelchair to transport her to their car. They then used the car to relocate her body from their high-rise apartment in the city of Darmstadt to a forest, where they disposed of it by rolling her down the hill, News.com reported.

Mrs. Khan said she was afraid to stop her husband [from doing the acts] because she was weak physically. But she affirmed her participation in the crime, said Bild.

The victim's 14-year-old sister, Nida, meanwhile, countered her mother's statement in the same courtroom saying, "She was not suppressed. She could do what she wanted. She used to hit me with a stick,'' according to News.com.

In his statement to the court, according to Bild, Asadullah said, "If I could do it undone, I would. My wife must obey me. I love my wife and my daughters."
