The police have arrested a young man for allegedly setting fire to three cars and a front door in Valletta, the second such arrest in just over a week.  

In a statement, the police said its Arsons Unit had carried out weeks of investigation following a spate of arsons between April and September.

Three cars had been set on fire, and another four were also damaged as a result.

The investigations led to the arrest of a 21-year-old man, who is also suspected to have set fire to a door. The man is expected to be taken to court later on Wednesday.

Inspectors Jeffrey Scicluna, Saviour Baldacchino and Priscilla Caruana Lee will prosecute. 

On December 3 the police announced the arrest of a man suspected to have masterminded several car arsons.

The 24-year-old from Zabbar was arrested after days of observation on the basis of information of a conspiracy to set a vehicle on fire.
