A woman was assaulted by two men while she was jogging around the Chestnut Hill Reservoir on Wednesday evening, according to Boston College police.

The victim, who has no affiliation with Boston College, told Boston College police she was hit in the head with a large tree branch just after 5 p.m.

The assailants fled on foot toward the DCR skating rink at the corner of Beacon Street and Chestnut Hill Avenue.

The Boston Police Dept. report determined it is unclear at this time if there was an actual assault.
