Cllr Mervyn Jones said: “This assault was despicable. It is a disgrace to think that people conducting work can be subject to a traumatic experience like this.
“The fact that one of the assailants was carrying a saw illustrates the sickening mindset of these thugs.
“People should be able to walk anywhere at any time without fear of assault and attack.
“I would appeal to witnesses and anyone driving through the area at the time to contact local police so that the culprits can be apprehended quickly.”
