A gunpoint robbery Monday morning at a coin collectors' store on Oakland's Grand Avenue led to a shootout between the thieves and the store owner, and in the exchange of gunfire a stray bullet entered a nearby residence and injured a person inside.

The robbery happened around 10 a.m. on the 3300 block of Grand Avenue in Oakland — the shop in question appears to be Northern California Coin Exchange, which is on that block. As ABC 7 reports, the store owner tells police that two armed men entered the store demanding valuable merchandise. After they took off with the goods, the owner, who apparently had a gun in the store, ran after the thieves and they exchanged gunfire.

The resident in a nearby home was injured by a bullet but is now in stable condition, as KTVU reports.

The thieves got away without being apprehended or injured, but they left behind whatever they had been trying to steal. Per KTVU, police have not disclosed what the valuable items were.

Oakland police are asking for anyone with knowledge of the crime to call the OPD's Robbery Section at (510) 238-3326.
