The Greek government maintains that that the fires were started deliberately by migrants protesting that the camp had been put in lockdown due to a COVID-19 outbreak amongst the migrants in the camp. On September 16, 2020, four Afghan men were formally charged with arson for allegedly starting the fire. Two other migrants, both aged 17, which is below the age of full adult criminal responsibility in Greece, were also allegedly involved in starting the fire, and were held in police detention on the mainland.
