Twenty-three-year-old Dennis Sullivan was attempting to rob what he
thought was an armoured car in Merseyside. In reality, it was a
laundry truck delivering towels and mops to a local store.
According to one police officer, "Holding a sawed-off shotgun, Sullivan
ran up to the driver and said, 'Give it up.'
The driver said, 'What?'
Sullivan grabbed a bag and ran off but soon realized he had a bag of mop
heads."
