Someone at a Maryland church hosting an annual Christmas show called emergency responders Saturday to request an ambulance for an unusual holiday season injury: a camel bite.

A caller reported around 2:10 p.m. that a camel had bitten a man on the arm while preparing for a production at Evangel Cathedral in the 13000 block of Central Avenue in Upper Marlboro, said Mark Brady, spokesman for the Prince George’s County Fire and Emergency Medical Services Department.

Paramedics don’t know what might have happened or the extent of any injury, Brady said, because someone canceled the ambulance before it arrived.

A woman who answered the phone at the church on Saturday declined to confirm or discuss the camel call.

The church’s website advertises a “Christmas celebration,” including a performance at noon Saturday, with more than 200 people in the cast of a “Broadway-style musical production.”

“Be amazed,” the website says, “as beautiful live camels, sheep and many other live animals set the tone for a surreal nativity scene.”

Last year’s Christmas Celebration at Evangel — its 25th anniversary — included three large camels leading a procession of live animals, colorful wardrobes and a cast of 200 people singing, dancing and telling the Christmas story through scenes extending from a New England town square to the cross on a hill called Calvary. It also draws well-known gospel artists and more than 27,000 guests each year, according to the church.
