UPDATE: Man Surrenders After Barricading Himself in Wheaton Home

Update, 1:23 p.m.: At 12:25 p.m., Montgomery County police took a male into custody for medical evaluation after he barricaded himself inside his home for nearly four hours, according to Officer Rebecca Innocenti.

Four officers arrived at the 12300 block of Livingston Street early this morning to check on the welfare of a potentially suicidal person.

After multiple attempts to contact the man, police called in crisis negotiators. At one point two police officers approached the single-family home, but had to back away.

Police will not comment if the man had a weapon and will not release his name.

During the incident, Randolph Road and several other streets were blocked. All roads are now open.
