Monday's arrest of a Jamaican by Immigration and Customs Enforcement (ICE) agents in Connecticut has sparked protest in the US state.
According to the CT Post newspaper, the Jamaican had just been arraigned on drug charges and was leaving the Golden Hill Street courthouse when two ICE agents arrested him.
On Tuesday, more than two dozen people, carrying placards picketed in front of the courthouse.
Many of the protesters accused judicial marshals, who stood watching the protest from the courthouse steps, of aiding immigration agents to detain undocumented immigrants.
This was denied by Donald Murphy, the director of state marshal services.
He said ICE, like any other law enforcement agency, can enter state courthouses to serve legal detainers or arrest warrants.
Since the beginning of the year, a number of undocumented immigrants have been arrested by ICE as they either left or were about to enter the courthouse.
