Police are investigating the death of a dog alleged to have been stolen during a walk then left on a railway track to die.

The 12-year-old Cairn Terrier-type dog, named Zak, was being walked by owner Janet Collins’ son, Ryan, who is described as a vulnerable adult.

They were walking along the Taff Trail between Mountain Ash and Penrhiwceiber when they were approached by three youths.

The three youths are said to have grabbed the dog’s lead and run away.

A huge search operation was launched after Zak was stolen with family and friends walking the trail in hopes to locate the dog.

Susan Grandon, a family friend who was leading the search, claimed the three youths then dumped the dog on a railway line where he was hit by a train and killed.

Hours after Zak was found dead the hashtag Justice4Zak was trending on Facebook and local residents have been changing their profile pictures in support.

Owners Janet and Ryan have asked for privacy as they grieve.
