AUGUSTA — A 46-year-old city man was scheduled to be arraigned Friday on an indictment accusing him of using an explosive to injure people last April.

Darren M. Ellis was arrested Thursday. He had been indicted in May on charges of criminal use of explosives and reckless conduct, but the indictment was sealed until his arrest.

Ellis was charged in connection with a plastic bottle bomb that was thrown following a night of fighting April 24 between a couple at a Washington Street apartment.

A woman suffered scrapes and bruises in the incident and was treated at MaineGeneral Medical Center in Augusta.

Two Augusta police officers who responded to the report of a domestic assault were treated at the same hospital for throat and eye irritation and returned to duty.

Ellis was arrested at the time on the same charges listed on the indictment.

Another man, Paul D. Glidden, 22, pleaded guilty in June in Kennebec County Superior Court to domestic violence in connection with the same incident and was sentenced to five years in jail, with all but nine months suspended, and two years probation. He was ordered to pay up to $1,000 restitution.
