A huge haul of class A drugs has been seized by police at Perth Prison.
Heroin worth £15,000 was recovered following a joint probe by Police Scotland and prison service bosses.
A 26-year-old man will be reported to the procurator fiscal in due course.
Police sergeant Dave Rice, from Perth’s Community Investigation Unit said: “We will continue to take action to tackle drug-related criminality and work with partner agencies to reduce harm in our communities.”
He urged anyone with information about the local drugs trade to get in touch.
The illicit stash was uncovered on Thursday amid a fresh crackdown on drugs at the jail.
More than £100,000 worth of drugs has been recovered at the compound since the police introduced a new prison liaison officer earlier this year.
A new report by Police Scotland has revealed that between April and September, six people were reported to the fiscal for trying to smuggle drugs into prison.
The anti-drugs campaign also focuses on the potential threat of drones being used to drop illicit substances into prison grounds.
The most recent available figures show there has been a fall in drug recoveries at HMP Perth in the last three years.
There were 136 finds in 2014, which fell slightly to 135 the following year.
In the first three months of this year, there were just 27 finds, including more than 100 miscellaneous tablets and 14 grams of class A heroin.
In recent years, the prison service introduced sniffer dogs at Perth’s visitor zone. Bosses also invested in new technology and trained staff to detect illegal drugs and paraphernalia.
Last month, data released by the prison service showed that HMP Perth was the worst in Scotland for incidents of serious assaults and fighting.
The rate of violence at Perth Prison has soared in recent months from seven incidents in 2014/15 to 13 last year, a five year high. The number of prisoner attacks at Perth is more than double the total recorded at Scotland’s biggest jail, Barlinnie.
Prison governor Brenda Stewart said that the figures did not paint an accurate picture of life inside the jail, which she said was a “very safe, controlled environment.”
A report which will go before Perth and Kinross Council’s community safety committee next week shows that the number of detections for drugs supply, production, cultivation between April-September has risen by nearly 20% from 55 last year to 65.
