Black bear delayed public schools opening, still ran free June 12

Reported earlier: The opening of all Arlington Public Schools was delayed one hour on Monday, June 12, after a bear sighting, schools Superintendent Elizabeth C. Homan reported in an email. A bear was seen in the Little Scotland neighborhood in Arlington Heights and at Wilson's Farm in west Lexington that afternoon.

A townwide phone call reported police noting a sighting of a black bear at Paul Revere Road and Park Avenue. The call said that town animal control and state environmental police were involved  -- and noted that bears can travel great distances in a short time.

Posters on the Arlington Email List cited a tweet from Arlington police as well as their own sightings, on Scituate and Cliff streets.

"The town is working on sending a shelter-in-place message," Homan wrote. "Residents should stay inside until further information is available. Please be watchful for updates over the next few hours. If you receive no further updates, elementary schools will start at 9 a.m., and Gibbs, OMS and AHS will start at 9:30." The schools have opened since then.

After 10 a.m., a helicopter whirred over Arlington.

At 1:26 p.m., Edwin Fields posted to the email list: "Black bear spotted on Inverness Rd in Little Scotland w/in last half hour."

Just after 2 p.m, Arlington police tweeted: "The most recent sighting of the bear was at Wilson’s Farm in Lexington."
