A man yelled ‘Allahu akbar’ seconds before attacking a couple at theย Oberhausen event in West Germany.

The couple were enjoying a picnic by the river when a man suddenly came up to them and started slashing them with their own knife. A 26 year old man was arrested by the police at the scene. He reportedly harassed several day-trippers before snatching a knife from the floor where the victims were. After further investigation he was found to be homeless and under the influence of drugs. Heโ€™s been takenย under custody and being held for psychiatricย evaluation.

The 66 year old woman is fighting for her life, while herย 57-year-old husband was seriously injured as he attempted to overpowerย the assailant.

One of the victims reported hearingย the attackerย shout ‘Allahu akbar’ as heย stabbed them, howeverย no other witnesses have corroborated hearingย the phrase and policeย donโ€™t believe the attack was politically motivated. Several people attending the event were treated for shock.
