[UPDATE] A bicycle delivery man is in critical condition after he was hit by a falling tree in Red Hook around 1 p.m.

According to ABC7, the Parks Department was cutting down a tree in Coffey Park near the intersection of Pioneer Street and Richards Street, but workers were unable to alert the cyclist in time that the tree was coming down.

The man was rushed to Methodist Hospital, where he is in critical condition. A tweet from the Daily News' Todd Maisel indicates that the street had not been roped off prior to cutting down the tree.

The park was reopened this summer after having been closed for a year for renovations.

We've reached out to the Parks Department for comment, and will update this story when we receive a response.

Also in Brooklyn, a 70-year-old woman was fatally struck by a BMW as she was crossing Atlantic Avenue near Grand Avenue in Clinton Hill today. A police officer was struck at the same intersection in December of last year.

Update, 4:36 p.m.: A spokesperson with the Parks Department says that the tree was being pruned by an outside contractor as part of the city's post-Hurricane Sandy cleanup, and that an investigation is currently being conducted.

She added that the department's standard safety protocols require cones, caution tape and a worker to flag approaching pedestrians.

The department also released the following statement: "Our thoughts are with the individual injured in this unfortunate accident. NYC Parks is conducting a thorough investigation of this incident. There is no further immediate danger to the public."
