A driver caught red-handed ferrying about £6,000 worth of class A drugs has been jailed for four years.
Leigh Johnson was stopped in Norman Avenue, Southall, by plain clothes officers when they noticed his driving was erratic.
They searched the black Vauxhall Astra and discovered 97 grams of heroin on November 4 at about 8am.
The unemployed 26-year-old from Southall was sentenced on January 15 for drugs offences.
A police spokesman said: "The illegal sale and supply of controlled drugs will not be tolerated and we will target these individuals peddling harm to the community.
"This sentence represents how seriously the courts regard such offences."
