Robert Walker caught with heroin bulking agent
A man has admitted storing 125kg of mixing agent that could be used to bulk out £8.75m of heroin.
Robert Walker, 29, was arrested following a police raid at his then home in Clydebank on 22 August last year.
No drugs were found but officers discovered five barrels of a mixing agent known as "Bash".
At the High Court in Glasgow, Walker admitted being concerned in the supply of heroin. Sentence was deferred.
Prosecutor Bill McVicar told the court: "Walker stated that he had agreed to store the barrels of powder for other individuals in exchange for £400.
"He said that he did not know what it was, but knew that it could be used to mix with drugs."
The court heard the powder was a combination of caffeine and paracetamol used to bulk out and reduce the purity of heroin.
Police said the powder could not have "any legitimate purpose".
Mr McVicar added: "This mix has become so desirable that a 'grey' market has developed to obtain it."
