It comes after a group of up to 15 young people threatened workers trying to stop them stealing plastic safety fencing.
A number of pieces of fencing has been burned in the area in recent days.
Councillor Duffy said: “I like many of the residents I have spoken to are appalled by this incident.
“A group of up to 15 young people threatened workers trying to stop them stealing plastic safety fencing.
“This must have been a very frightening experience for these workers who are just in doing a day’s work and stopping vital safety fencing from being stolen.
“They should be able to work free from threats or harassment.
“I have been campaigning for a long time for a gas supply to this area.
“The last thing we want to see is workers having to leave due to threats and the installation of a gas supply into local homes to stop.
“I have been in contact with the PSNI and the company in relation to these threats,” she added.
