The body of Liam Smith, 38, was found outside his home on Kilburn Drive in the quiet village of Shevington on the evening of November 24.

A post-mortem examination would later conclude that the businessman, who was born in Chorley and attended Holy Cross High School, had suffered a fatal gunshot wound and been covered in both acid and alkali in perhaps a cack-handed attempt to obscure his identity.

On Thursday January 19 police announced that they had arrested a 35-year-old man in Sheffield on suspicion of conspiracy to murder Mr Smith and he remains in custody for questioning.

His as-yet-unidentified body had to be kept in situ far longer than is normal practice after its discovery because of the fears of contamination from toxic substances which were later declared a low risk to the public.
