Craig Thomson was stripped naked and searched by prison guards on the NSW Central Coast in an attempt to intimidate him, the embattled federal MP's lawyer says.
Chris McArdle, who is representing Thomson in his fight against 149 fraud offences, made the claim on Thursday night.
He said Thomson, 48, was strip searched by two prison guards after being arrested via a warrant from Victoria Police about 1pm (AEDT) on Thursday at his electorate office at Tuggerah.
"These two goons put on rubber gloves, one stood in front of him, one stood behind him, and they said `take off your shirt'," Mr McArdle told Network Ten.
"They examined his shirt to see if there were any molotov cocktails.
"He had to take all of his clothes off and stand naked in front of these two galoots who then took him into the court and sat each side of him."
Mr McArdle described the treatment of his client as "absolutely extraordinary intimidation of an innocent man".
The former Labor member represented himself during a brief bail application in local court that police did not oppose.
Outside court, he made a brief statement and did not take questions even though it went "against the grain" as a politician.
Court documents state the alleged offences occurred between February 2003 and April 2008.
Thomson's matter will come before Melbourne Magistrates Court on Wednesday.
