The FBI is releasing little information about a “shooting incident” that law enforcement says occurred Thursday afternoon in Ryegate.

The agency stated in its statement that one person was detained, but the name of this person or the charges, if any, he may be facing were not specified.

According to the FBI, the incident occurred at 1:15 p.m. Thursday on Route 5 in Ryegate and “involved the alleged assault of a federal officer (U.S. Marshal).”

The one-paragraph statement mentioned a “shooting investigation” but did not say who fired the shots or whether anyone was injured.

“To protect the integrity and capabilities of the investigation, we will decline to provide further details at this time,” the FBI said in a statement.

FBI spokeswoman Sarah Ruane in Albany did not immediately respond to phone and email messages Friday.

John Curtis, chief deputy to the U.S. Marshal in Vermont, declined to answer a series of questions about the incident Friday morning.

“We have no comment at this time,” Curtis responded in an email.
