Forestry official Tun Tun Oo says the 7-year-old female was captured by his department on Friday, six weeks after it was initially spotted in a reserve in Pathein township.
"We had to be careful," he said. "It's wild. We didn't want the elephant or the forestry department officials to get hurt."
White elephants, actually albinos, have for centuries been revered in Myanmar, Thailand, Laos and other Asian nations.
Often pinkish in colour, with fair eyelashes and toenails, the animals were normally kept and pampered by monarchs as a symbol of royal power and prosperity and many people still believe they bring good luck to the country.
