The Immigration and Customs Enforcement agency says it’s investigating how a Cameroon national with no criminal record was arrested and nearly deported after his American wife wrote a letter asking President Obama to help with his bid for asylum. Immigration agents arrested Hervé Fonkou Takoulo outside of his Manhattan home earlier this month. Takoulo’s wife, Caroline Jamieson, had written Obama a letter in January requesting assistance in her husband’s case. Takoulo was facing an outstanding deportation order after being denied asylum. The couple did not receive a reply to the letter until the agents showed up to arrest Takoulo. He was released from an immigration jail last week following inquiries from the New York Times. Takoulo still faces deportation. Immigration officials say they’re probing how government standards of not using letters requesting help to fuel arrests and not arresting deportable immigrants without criminal records were violated.
