'Cat pee' smell mystery at Vauxhall plant lingers on
A walk aimed at identifying a "cat pee" smell plaguing residents near a motor factory has failed to find the cause.
Some people living near the Vauxhall plant in Luton have complained that they have to shut their windows all year round because of the stench.
The company invited residents to join officials on an "odour walk" to trace the problem, first reported in 2011.
But instead they found a "rotten egg" smell. Vauxhall said it was unrelated to the other problem.
A company spokesman said: "Earlier in the year, two residents who had complained about the cat pee smell stated categorically that the rotten egg odour was not the smell that they had been complaining about."
Vauxhall said it would continue to attempt to find the cause, with four-mile tours taking place daily around the plant, visiting 29 points.
The Environment Agency said it had carried out at least 23 inspections since receiving the complaints about a smell of cat urine. It said the odour was likely being produced by bacteria in stagnant paint.
Claire Richards, from the agency, said notices had been served on Vauxhall to eradicate the odour.
