A person is being held following a shooting at a Minnesota clinic in which multiple people were shot, US police said.

The shooting happened at the Allina clinic in Buffalo, a city of about 15,000 people roughly 40 miles northwest of Minneapolis, Kelly Prestidge, an office manager for the Buffalo Police Department, said.

Ms Prestidge said one person was taken into custody, but that she did not know if it was the gunman.

She also said she did not have further information on the attack, including how many people were shot or if anyone was killed.

Buffalo Police Chief Pat Budke told TV station KSTP that the shooting happened inside the Allina Clinic Crossroads campus.

He said the situation was contained and that there was no further threat to the public’s safety.

The Midwest Medical Examiners Office, which handles cases in Wright County, had no comment on whether it had sent anyone to the scene.

The FBI did not immediately respond to a message seeking information.

A spokeswoman for the Bureau of Alcohol, Tobacco and Firearms said members of its enforcement group were heading to the scene.
