A 15-year-old boy is now in custody in connection with a fatal shooting at Northtown Mall in Blaine last week.
The Anoka County sheriff's office is not saying what charges are filed against the teen.
Earlier this week a 20-year old man was charged with aiding an offender to avoid arrest in the killing of a Brooklyn Park teenager.
Authorities say they are still in search of a 14-year-old boy who they believe was involved in the shooting that around 5:00 p.m. last Friday.
The victim has been identified as Sudais Abdi Omar of Brooklyn Park.
The mall was put into lock down during the incident.
