It is very common for “mules” to swallow balloons of heroin or other narcotics — only to be put under observation until they “produce” the evidence. It is one of the least glamorous jobs for police officers. However, Damien Ankrah, 28, showed remarkable tenacity in a case in England where he refused to go to the bathroom for 16 days — clearly hoping that the police could not hold him indefinitely without evidence.
The problem for the drug dealer arrested in Haverfordwest, Pembrokeshire, became apparent when police showed him an order extending his confinement. He then agreed to eat and drink and produced five bags of heroin.
He could consider himself fortunate. It is not uncommon for mules to die when these bags open in their stomachs during flights or trips, here and here. One dealer died in London of choking on such bags, here.
