Police said they were called yesterday, Friday, May 6, at around 6pm, to reports that a number of males had broken into the substation on Aldham House Lane, in Wombwell, Barnsley, and stolen a digger, before leaving in a white panel van with the digger attached on a trailer.
Officers spotted the vehicle soon after in Darfield and gave chase before the vehicle was abandoned and the occupants fled on foot.
One man, aged 40 and from Doncaster, was detained in a nearby field and today remained in police custody.
The digger was recovered along with the van, which turned out to be displaying false plates and had been stolen from the Premier Inn hotel in Doncaster in February.
Anyone with information is asked to call police on 101, quoting investigation number 14/84716/22.
