A man in his 40s was left with life-threatening injuries after falling from the third floor in Hässelby gård, Stockholm, late on Saturday.
A witness spotted the man on the ground and alerted police at 22:52 on Saturday. The man was taken by ambulance to hospital.
A man in his 50s and a woman in her 40s were detained in the same building. They are suspected of attempted murder.
Police spokesperson Ola Österling said they were arrested right after being interviewed. It is not yet fully clear exactly where the man fell from, though suspicion points to a nearby balcony.
