The lawyer for an ultra-orthodox Jewish sect says six members have been arrested by the Canada Border Services Agency over suspected immigration issues.

Lawyer Guidy Mamann says CBSA agents went looking yesterday for seven Lev Tahor members who had either been ordered removed from Canada or had their status expired.

Mamann says five of those people, as well as one other person who was found to have alleged immigration issues, were apprehended in Chatham, Ont.

He says he's working with CBSA to ensure the two other people authorities had been seeking comply.

Some families in the Lev Tahor community are at the centre of an ongoing child custody case, but a community member says those arrested are not involved in the child welfare case.

Mamann says the community was terrified during the CBSA arrests, as about 20 armed officers went from house to house looking for adults and children.

He says he's hopeful that some of the adults who were apprehended will be released quickly by CBSA.
