Police patrols are to be stepped up in Monifieth following three nights of fire-raising.
A gang of teenage vandals is being blamed for a series of blazes in the town.
Fire and rescue officials, residents and politicians have all spoken of their determination to see the culprits brought to justice.
Firefighters have been called out to attend three blazes, believed to have been started deliberately, in and around the Riverview Caravan Park and Blue Seaway playpark area.
Residents posting on community page Our Monifieth have also reported seeing a group of around 12 to 15 teenagers setting aerosols alight and are appealing for information.
On Monday night firefighters tackled a fire in the bushes near to the railway line, the following night a traffic cone was set on fire at the caravan park and on Wednesday night crews spent 15 minutes putting out a 50 metre strip of dry grass near the beach.
One female holidaymaker told The Courier she had smelt smoke on Tuesday evening.
She said: “The next night there were groups of teens on the beach having a party and throwing things on a fire trying to get them to explode.”
A spokesman for Scottish Fire and Rescue said the frequency of incidents is unusual for the area and the most likely cause was wilful fire-raising.
Local risk manager for Angus West, Graeme Nicoll said: “It’s fairly unlikely for a traffic cone to spontaneously combust so it would appear to be wilful fire-raising.
“We need to get this behaviour stopped. The consequences of playing with matches and trying to light aerosol cans could be severe and injuries could be nasty.
“Parents need to have an awareness of where their kids are and what they are doing and if they come home smelling of smoke challenge them on it.
“If we can’t nip this in the bud one of these kids will end up hurting themselves and that will be when they get the message.”
He said the fire service will be looking at the issue closely and working with police and local schools to tackle the problems.
Chairman of the local community council John Whellams said that to have incidents three nights in a row was worrying.
He said: “I think it’s disgraceful. It is one thing making a noise but it is quite another having three nights of setting fires. That sort of thing can quickly get out of hand.
“The people living nearby will wonder if they are safe.
“It only takes one gust of wind to lift something on fire and take it into the caravan park or someone’s garden to make it a lot worse.
“To do it once and get away with it is bad enough but to do it a second and third time seems it is now getting into a dangerous pattern where they are getting more daring.
“I dread to think what will happen next.”
He said he would be contacting the area’s community police officer to see what can be done.
Local councillor Rob Murray appealed to the fire-raisers to stop before it is too late and urged anyone with information about those responsible to contact the police.
A Police Scotland spokeswoman confirmed they are aware of the issue and would be stepping up patrols in the area in response.
