He was identified in court only by the name "Deano". The police officer had been part of an undercover operation in Basildon, Essex, last year to target an alleged gang of drug dealers. He had posed as an addict to infiltrate their operations, but when they became suspicious, the court heard, the gang leader looked into the "white of the officer's eyes" and asked him if he was "Old Bill". Deano was savagely beaten, whereupon the secret camera he was wearing was discovered. He said he only managed to escape with his life by jumping from a window.
