An anti-racism campaigner said he was "absolutely shocked and quite horrified" to receive a text message from the Home Office warning him he "may not have leave to remain in the UK."
Suresh Grover, founder of The Monitoring Group, told The Independent, "I thought it wasn't meant for me. I came here with my parents in 1966, I was born in East Africa and have always had a British passport."
Mr Grover, who called the number on the text and spoke to someone at private contractor Capita, said: "The more I talked to the woman the angrier I got. She was asking for more personal information about me and was not telling me where she got my number.
"I think it's outrageous sending people random texts without knowing who they are sending them to ... it's horrific."
