An ALK Airlines Boeing 737-300 on behalf of Congo Airways, registration LZ-LVK performing flight 8Z-112 from Goma to Kinshasa (DR Congo), was climbing out of Goma when the crew received a cargo hold smoke indication and decided to return to Goma for a safe landing. Emergency services found a suitcase showed signs of heat damage and found a Powerbank (LiOn Battery) in the suitcase which had suffered a thermal runaway.

LiOn Batteries are not permitted in checked luggage but must be carried in the carry-on luggage.
