Police arrested the 22-year-old mother and her 41-year-old husband after a prison visit security check last Thursday, during which they found 15 grammes of amphetamines and 46 ecstasy pills in their 17-month-old daughter’s diaper. The mother also had 12 grammes of amphetamines hidden in her clothing.

The family had come to visit the woman’s father, who is an inmate at the facilty. But the drug find rendered the “visit to father and grandfather no more,” a police report said.

During their investigation of the incident, police discovered clues to a Siegburg couple already in the sights of local police. Fourteen officers with dogs searched their mobile home at a camping area and found 166 ecstasy pills, 530 grammes of amphetamine paste, 60 grammes of amphetamines and a Browning pistol with ammunition.

The 61-year-old man and 59-year-old woman were arrested but later released after giving statements, police said.
