Spanish police have arrested Saturday in Madrid a Bulgarian who threw a woman out of the window and then threatened another woman.

A heated argument between the 26-year-old Bulgarian and a woman in a second floor apartment led to the murder of the woman, witnesses have told Spanish media. After the accident the Bulgarian ran away from the scene.

He then entered a bar, where he threatened to kill himself and knife another Bulgarian woman who was saying the man had just killed someone. Police managed to subdue him and take him in custody, where he confessed to the murder.

Police are still trying to determine the man's connection to the two women.
