A Bethlehem man was charged Friday in a break-in attempt last September at the 1920s Archibald Johnston Mansion owned by Bethlehem Township, according to court records.

The incident caused nearly $1,200 in damage, according to police.

Michael P. Ohm, 21, of the 3100 block of East Boulevard, allegedly tried several ways to break into the vacant home about 3:30 p.m. Sept. 19.

He used a metal bar to break the locks and a door, setting off the interior alarm, police said.

Built for Johnston, who was a Bethlehem Steel Corp. executive and the city’s first mayor, the mansion is part of acreage left to the township by his daughter and her husband. The public land is known as the Janet Johnston Housenick & William D. Housenick Memorial Park at 3811 Christian Spring Road in the township.

Ohm was arraigned Friday morning before on-call District Judge Jacqueline Taschner on a charge of defiant trespass and two counts of criminal mischief.

He was sent to Northampton County Prison in lieu of 10 percent of $5,000 bail.

If released on bail, Ohm would have to remain under the supervision of Northampton County Pretrial Services and stay off the Housenick property.

A preliminary hearing is tentatively scheduled June 2 before District Judge Anthony Rapp Jr.
