The police surrounded a house in South Yarmouth on Friday and ordered 31-year-old Shaun Miller suspected of drug trafficking, out.
He walked outside in disguise and when they realised the "elderly man" was actually who they were looking for, they arrested him.
"Upon further investigation, officers determined that the 'elderly man' was in fact Miller," CNN quoted Yarmouth police as saying in a statement.
"At that point, officers pulled off Miller's realistic disguise and placed him under arrest," the statement said.
Two loaded weapons and almost $30,000 in cash was seized from Miller.
Miller is scheduled to appear on August 31 at US District Court in Boston, CNN added.
