TWO men aged 28 and 31 were arrested in Larne on Tuesday night following a spate of arson attacks.
The pair were arrested on suspicion of arson with intent to endanger life.
Residents in the Co Antrim town were said to be "living in fear" after a string of attacks, including one on a hairdressing salon on Monday night.
A car was reversed into metal shutters at the town centre salon and set on fire at around 9.20pm on Monday. The blaze extensively damaged the premises.
It's believed one man travelled to the scene in the car, a grey Nissan Primera, and then fled on a blue and white motorcycle driven by a second person.
Detective Chief Inspector Dunny McCubbin said: "This was a mindless and reckless attack by individuals who have shown no concern for the people of Larne and no respect for the business people trying to make a living in the town. This business has been devastated by this attack and there can be no excuse or justification for what happened here last night."
Police said they are investigating a possible link between the attack on the salon and other attacks on vehicles in the town.
Early on Monday morning, cars were set on fire on Bryan Street and Mill Road. The front window of a house on Mill Road was also smashed. Police said a petrol soaked rag, possibly from an unlit petrol bomb, was found on the house's porch roof.
Six cars were targeted in a spate of arson attacks in the early hours of Saturday and Sunday. Five of the cars were extensively damaged.
"The whole community is living in fear," said Alliance MLA for East Antrim Stewart Dickson.
"The range of incidents - from cars to town centre premises - cannot be allowed to escalate further and I would urge anyone with information to speak to the police immediately," he told the BBC's Good Morning Ulster programme.
Detective Chief Inspector McCubbin said:"At this time it's thought a falling out between two individuals may be the catalyst for these incidents however as the investigation is at a very early stage it wouldn't be appropriate to comment further on that particular line of enquiry.
"To date two men in their thrities have been arrested as part of our overall investigation. A 30 year old man was arrested on Saturday and subsequently charged with GBH and Possession of an offensive weapon. He is expected to appear in court in Ballymena on 11 May. The second male, 32, was detained yesterday. He has since been charged with Common Assault and Making threats to damage property. He is due to appear at Ballymena Magistrates on 4 May."
