UPDATE: Police search undergrowth for evidence as part of Owen Dunn murder probe
Specialist search officers have set up near an old canal in Swindon this morning (Wednesday).
Parked on The Eastern Flyer, two Wiltshire Police vans and a dog unit are in attendance off Ocotal Way. 
Two tents and numerous chairs have been erected in a field off Pitt Close, close to an abandoned canal.
At least a dozen police officers were seen at the location by witnesses passing the area.
It’s not yet known why there’s a police presence, but it could be for a training exercise.
Wiltshire Police has been approached for comment.
