A 16-year-old born in Chechnya confessed to the murder of a seven-year-old girl in Vienna this week after he lured her to his home where he stabbed the child in a bathtub because he was “having a bad day”.

The 16-year-old, identified as Robert K., is said to have invited seven-year-old Hadishat, who lived in the same apartment complex in Vienna’s Döbling district, to his family’s apartment Friday and stabbed her in the neck until she died, Kronen Zeitung reports.

Hadishat had been playing with other children in the apartment complex courtyard before the murder and was well-known to both the murderer and his family as she had previously visited the apartment to play with the family’s cat.

Following the murder, the teen Chechen, who is an Austrian citizen and has lived with his family in Austria for several years, placed the young girl’s body into a large garbage bag and threw her in the apartment building’s garbage bin.

The victim’s 17-year-old brother called the police hours after she had disappeared and her body was found the following day by a waste management employee who saw her feet protruding from the dumpster.

Robert K. was not arrested for the murder until Tuesday and according to sources close to the investigation told investigators that he was motivated by the fact that he was having a “bad day” at the time.

The murder comes less than a week after another Chechen migrant in France stabbed and killed one and injured several others in Paris over the weekend. The man, identified as 29-year-old Khamzat Azimov, was also on the “S-File” terror watch list.

The attack came only months after German historian Christian Osthold claimed that Chechen migrants were rapidly taking over the radical Islamic extremist scene in Germany.
