Unknown assailants broke into a wood-processing factory in the western Athens suburb of Ano Liosia early Monday, stealing a safe and several electronic devices, police said.

The burglary occurred around 5 a.m. at a facility on Alexandrou Avenue, authorities said. The suspects reportedly broke through a wall to gain entry.

Once inside, they removed a safe along with six computers and uninterruptible power supply (UPS) systems before fleeing.

Police are investigating. No arrests have been reported.
