The body of a burned cat and a message directed to President Barack Obama were found in Longfellow Park, city and federal officials said.

Minneapolis police, the FBI, the U.S. Secret Service and other agencies responded to the message a parks employee found Monday near the Longfellow Park and Recreation Center, a voting location used in Tuesday’s primary election.

Dawn Sommers, spokeswoman for the Minneapolis Park and Recreation Board, said the cat’s body was found with a political message attached to it at the south end of the park.

“At this point, it is undetermined the direction the investigation will go,” Sommers said in a statement. “Given the political message, it may involve additional agencies.”

The Secret Service handles threats against the president, and a representative with its Minneapolis field office said the agency responded to the incident.

“We are monitoring the situation and will take the appropriate follow-up steps,” said Louis Stephens, special agent in charge with the Secret Service in Minneapolis. “To our knowledge there wasn’t any other message or written communication of a threatening nature at the scene or relating to the incident.”

Kyle Loven, a spokesman for the FBI, said his agency was aware of the incident and would provide support if called upon.

Meanwhile, the Minnesota Federated Humane Societies is offering a $1,000 reward leading to the arrest and conviction of the person or persons responsible for the cat’s death. Callers can remain anonymous. If you have information, call 612-866-8663 or 1-877-8ANIMAL, toll-free.
