Police investigators have yet to enter a property in Dhali that was badly damaged from what appears to be a rocket attack early on Sunday morning.
“We are not allowed in due to safety concerns,” a police spokesman said.
He added that there were fears the structural integrity of the building had been compromised by a fire that followed the explosion.
Police said they have identified the position from where the rocket was launched but had not yet determined its type.
The force’s explosives’ experts have reduced the list down to 10 but it was too early to say whether the weapon could be found in the National Guard’s arsenal.
The building was used as a warehouse where alcoholic drinks and water were stored by a company linked to Andreas Rodotheou who was gunned down in April while at a friend’s house at the village of Gerasa, Limassol.
The 61-year-old was shot while standing behind a sliding glass door.
The shooter or shooters, apparently laid in wait on the opposite bank of a river that passes through the area.
Police have no leads concerning the perpetrator.
