A building in New Haven partially collapsed on Friday afternoon, trapping five people inside, a city official confirmed.

A spokesman for Yale New Haven Hospital said the facility was treating treating seven patients and expected an eighth to arrive. Six of the people were being evaluated and treated; one was listed in serious condition, the spokesman said.

Multiple emergency crews are responded to the building on Lafayette Street which is located at a construction site, said Rick Fontana, New Haven’s director of emergency operations.

According to Fontana, people initially were trapped inside after the second floor dropped onto the first level. All of the victims were rescued as of 1:50 p.m., according to first responders at the scene.

Fontana said that six people were injured, according to WTNH. A spokesman for Yale New Haven Hospital said the injured victims would be transported there.

According to Fontana, the building site is owned by Yale University but was leased to RMS, a commercial real estate developer.

Representatives from Occupational Safety and Health Administration (OSHA) responded to the scene of the incident.
