GARDAI have launched an investigation into the suspected arson attack on a Baldoyle tyre business last week.
The building, belonging to Baldoyle Tyres and Motor Factors, was completely gutted by fire last week.
Two Dublin businessmen had just moved into the premises four months ago.
Billy Gill and Philip Browne ran Baldoyle Motor Factors and Baldoyle Tyres in the Baldoyle Industrial Estate and shared the same building.But their businesses, which operated under one roof, were destroyed by fire on Tuesday.
Gardai in Howth have now asked for the public's assistance in relation to a "serious suspected arson" which occurred at the Baldoyle Industral Estate.
The businessmen told the Herald how they were stunned to discover their livelihood was up in flames. Billy said that he used to have a business around the corner but he got the opportunity to move in with Philip around four months ago.
"I am just gobsmacked. I don't know where to start," he said. "A friend saw on Facebook on Tuesday evening that it was on fire and rang me.
"I came down straight away. All I could do was tell them of the different chemicals and flammable products inside and where they were, and then I just had to leave them to it."
"We have no idea yet what caused the fire, but I really don't know where I go from here or how to go about getting going again," he added.
"I have a wife and two children to support so I have to do something."
Philip Browne started in business at the site in the summer of 2012.
"It was going well, especially when Billy came in, and now I just don't know what to do. I don't know where this leaves me," he said.
"We have been getting great support from the community here, which means a lot to us."
The fire also proved devastating for customer Laura Stacey, who left her car in for repair
"The car is just a 2006 Fiesta but it's my little run-around and I loved her," she said.
"It is very smoke-damaged and probably a write-off, but my heart really goes out to the lads. They have lost their livelihoods just before Christmas."
