A British term, means formally charged with an offence. Police compile evidence and/or arrest a person. If the Police think there is enough of a case, the Crown Prosecution Service (CPS) decide if there is enough evidence to support a 'charge'

Basically Police arrest, looked at the evidence then took no action as Police decided no crime - therefore not charged.
