Yes it is. The police arrest a person and make initial charges, but the official charges are filed by the prosecutors. The State can choose to drop charges even though the police made an arrest. Likewise, the State may determine the police "under charged" and file higher charges. Be sure to have an attorney prior to arraignment or at least hire one immediately after. You don't want too much time to go by without one. Besides, you almost never should plea guilty or no contest at the arraignment anyway.
