Warders at Kingston Prison in Portsmouth initially took prisoners' enthusiasm for collecting tennis balls accidentally knocked into the yard as a sign that Wimbledon fortnight was imminent.
It was not until random testing revealed that 35 per cent of inmates were using drugs that it was discovered that the tennis balls contained cannabis and had been hit over the wall by friends of inmates.
The scam was revealed yesterday in a report by Her Majesty's Inspectorate of Prisons that highlights measures the prison has taken to stamp out drug misuse in the past year.
At the beginning of April 2006 the number of inmates testing positive for drugs was down to 12.9 per cent - just above the national prison average of 10.3 per cent.
