The police van we were following had taken an unexpected turn down a road of privately owned detached houses and bungalows.
It didn't feel like the kind of place where you would normally witness a dawn raid by the serious and organised crime unit.
Yet within minutes the street's peace and quiet was shattered by the screech of glass cutters, the baying of startled dogs, then shouts of "police."
The house in Barrhead, south of Glasgow, was one of 13 addresses targeted by a Police Scotland campaign against alleged members of a newly identified crime group. The dawn raids led to eight arrests.
Operation Silhouette now has a total of 36 arrests, the seizure of cocaine and cannabis worth £6m, and the discovery of £1.5m in cash.
