London - A pair of vintage trainers missing since the Olympic Marathon are in the frame for last night's Greenwich foot tunnel closure.
Dave Snargs and fellow running coach Alf Rancid are suspected of causing the stink that shut the Thames underpass some 50 feet under the river.
The men were caught on CCTV 'giving off fumes' that resulted in seven pedestrians being taken sick.
Police, fire and ambulance services at first suspected a stink bomb had nauseated the walkers who became breathless around half past six.
"It was around the time that the daft Kathryn Jenkins 'I-didn't-shag-Beckham' story broke," a paramedic commented.
"Nauseating stuff but hardly toxic."
Eventually some contaminated Odour Eaters were discovered and blamed for the stench that reporters likened to sewage.
