A Texas nun who was taken into immigration custody last month while walking to Sunday Mass in her habit has spoken out for the first time.

Sister Leticia Ugboaja was released several hours after being detained on 28 June by US Immigration and Customs Enforcement officers in a town near the border with Mexico.

“Honestly, in that moment, I did not understand what was going on, what was happening to me,” she said at a news conference at Our Lady of Sorrows church in McAllen.

“Sunday Mass is obligatory … For me, a nun, not to go to mass on Sunday, not to receive communion, It was very, very heartbreaking for me,” she said.

Ugboaja said she wanted to speak out to help others, and pleaded for people to have the chance to be heard before being taken into custody.
