Photos capturing dramatic scenes of Finland's first-ever airline hijack
In the autumn of 1978, a dramatic airline hijacking took place in Finland - it was the first ever plane hijacking in Finland.
The scenes at Helsinki airport were captured by photographer Hannu Lindroos, which are now part of the collections of the Finnish Heritage Agency.
Finnair Flight 405 - a domestic flight between Oulu and Helsinki with 44 passengers - was hijacked on 30 September 1978 by Aarno Lamminparras, a 37-year-old unemployed building contractor.
Threatening the cabin crew with a loaded pistol, Lamminparras demanded ransom money and forced the pilots to fly the plane between Helsinki and Oulu. With ransom money paid and some hostages released, Lamminparras then demanded that the pilots fly to Schiphol airport in Amsterdam, where the plane refueled.
Then, returning to Helsinki, the remainder of Lamminparras's ransom demands were met and more hostages were released. Then the plane returned to Oulu.
Lamminparras's final demands included four bottles of whiskey, a chauffeured limousine and 24 hours alone at home with his wife. Having agreed to this, the final hostages were released. Lamminparras was arrested at his home on 1 October 1978, and later sentenced to seven years in prison.
As this was the first time this had happened in Finland, the event attracted a lot of media attention, which Lindroos's photography captures.
