SANTA FE, N.M. (AP) — The downtown post office in New Mexico's capital city is locking up its lobby overnight because homeless people have taken to finding shelter there.

Postal Service spokesman Peter Hass says the overnight closure of the downtown Santa Fe post office's lobby stems from vandalism and safety concerns voiced by customers.

The Santa Fe New Mexican reports that the closure between 10 p.m. and 6 a.m. beginning Wednesday comes as chilly overnight temperatures begin to cause homeless people to seek refuge indoors.

Assistant Director Sue Carr of the Interfaith Community Shelter in Santa Fe says more people are spending the night at the shelter as the weather gets colder.

The shelter's overnight capacity is 123 people.
