BRUNSWICK, Maine — Local police have increased patrols in a local park after noticing “a lot” of recent sexual activity — and suspected prostitution — in the wooded area.

A handful of summons — most recently for indecent exposure on Thursday afternoon — have been issued at Sawyer Park, a recreation area and boat launch off Bath Road along the New Meadows River.

Just after 3 p.m. Thursday, Deputy Marine Warden Paul Plummer was walking on a path along the shoreline when he allegedly encountered Henry Martinez, 30, of Santa Fe, N.M., engaged in a sexual act with 72-year-old Richard Withee of Brunswick, Deputy Chief Marc Hagan of the Brunswick Police Department said Friday.

Martinez and Withee each were charged with indecent conduct, a misdemeanor.

Hagan had no specific numbers immediately available, but said police have seen an increase in activity of a similar nature in Sawyer Park over the last few months.

“We do suspect that a certain amount of it is prostitution,” he said.

Police have not charged any of the handful of people summoned — all of them men — with prostitution, but Hagan said, “People are reluctant to say money has changed hands.”

He said not everyone officers have encountered were charged.

“Some people aren’t as brazen as others,” he said.

Employees of Brunswick Parks and Recreation, who maintain the park, have worked to cut back brush in the area in an attempt to deter such activity, Hagan said, and police have increased patrols.
