A goat’s head was delivered to Wrigley Field on Wednesday afternoon, addressed to Cubs owner Tom Ricketts, and police are investigating the dropoff of the “intimidating package,” officials said.

Cubs spokesman Julian Green said an unidentified person dropped off a package with a goat’s head at Gate K of the ballpark at 1060 W. Addison St.

The head was all black and had a U.S. Department of Agriculture tag on its ear, a police source said.

It was delivered by a man who drove up to the ballpark's security gate, the source said. The man gave the package to a security guard and asked him to deliver it to Tom Ricketts, the source said. The man then got back into his truck and drove away.

The package, which did not contain a note, was never delivered to Ricketts, the source said.

Police were called to Wrigley Field at about 2:30 p.m. because of the “intimidating package,” said Police News Affairs Officer Veejay Zala.

Police gave the goat's head to the city's animal control department, the source said.

The Cubs are in the middle of highly publicized negotiations with city officials and neighborhood interests regarding proposed changes at the ballpark, including whether the team should be able to install a Jumbotron-like scoreboard and increase the number of night games from 30 to about 40.
