Another minor is suspected of involvement in the shooting at Kungsmässan in Kungsbacka, reports SVT Halland.
Four people under the age of 18 are now suspected of the shooting that occurred in the midst of the shopping rush at the mall in early October.
Previously, two 14-year-olds have been taken into custody suspected of two cases of attempted murder and gross weapons offense, respectively, and aiding and abetting attempted murder.
Earlier in the week, a person under the age of 18 was also arrested.
A 25-year-old man was injured in the shooting. To TT, the prosecutor Viktor Törneke has said that it is likely that there was a client in the background.
I am of the opinion that two 14-year-olds did not do this on their own, said Törneke then.
The shot man is known to the police from before. According to Kungsbacka-Posten, three armed men were arrested outside his residence last summer.
