GRAND HAVEN, Mich. (WOOD) — Charges have been issued against a fourth suspect and Grand Haven police continue to seek a fifth in an armed robbery at a cellphone store last month.

Glasco was ordered held at the Ottawa County Jail without bond.

Alonte Coleman, 17; Yaceair Divers, 16; and 15-year-old Ibrahim Dadiri have already been charged in the Aug. 18 robbery at the T-Mobile store off US-31 north of Jackson Street.
