A Spanish official says a five-month old baby died  the Alicante airport in southeast Spain after becoming trapped on a luggage conveyor belt.

A spokeswoman for airport management company Aena said the baby and its American mother arrived at the airport late Wednesday on a flight from London. She said the father, a Canadian, was waiting for them at the airport.

“The mother apparently put him down on the conveyor belt when she went to reach for something,” the worker told Atlas news agency.

The Spanish Guardia Civil is investigating the incident.

Police said they were investigating. The U.S. embassy in Madrid said it was aware of the incident but could not provide further information.
