A man has died after two stabbings which police have described as “potentially linked and targeted”.
He was found injured after police were called to a block of flats in Shooters Way, Basingstoke, at about 22:45 BST on Saturday. He died later in hospital.
A second man was taken to hospital with serious stab wounds after being found in nearby Normanton Road minutes later.
Two men aged 29, a 36-year-old woman, all from Basingstoke, and a 16-year-old boy from Croydon, have been arrested.
The alleged offences for which they were detained have not been revealed by police, who said a murder inquiry had been launched.
Officers said they were called to a “report of a disturbance” at Kingfisher House in Shooters Way, next to South View Junior School.
Det Ch Insp Dave Storey said: “We are treating these incidents as potentially linked and targeted events.”
A cordon is in place while officers carry out house-to-house inquiries.
