The incident took place on Monday night in Limassol, following Orthodox Easter Sunday.
Police say they were notified of the incident just before 1am on Tuesday morning, when they got a witness account saying the explosion was due to a firecracker explosion that took place around 10pm on Monday.
The victim had to have his left hand amputated at the wrist, while he also sustained multiple wounds and abrasions on his body.
Police say they are investigating the incident, adding that this is the most serious case during this year’s Easter celebrations.
Despite police trying to clamp down on the illegal possession, use and trade of firecrackers over Easter, people still complain about unlawful firecrackers wreaking havoc in their communities and neighbourhoods even after Sunday’s traditional lambradjia.
