Police at the Florida state Capitol refused to allow food deliveries on Saturday to a student group that has been engaged in a sit-in there for the past 12 days, before apparently reversing their decision hours later.

The Miami Herald reported on Saturday that a delivery to members of the Dream Defenders around 2 p.m. was turned away by authorities.

"We knew this wasn't going to be easy," the group's leader, Phillip Agnew, told the Herald. "But if we don't get some food soon, we are going to have a lot of really hungry people."

About 60 members of the group were inside the building at the time of the delivery. Agnew said to the Herald that they could run out of food and bottled water by Sunday morning, but a state law enforcement spokesperson told the newspapers that meals were still able to be delivered to the protesters.

The demonstrators used their Twitter account to encourage supporters to call authorities on Saturday afternoon, before reporting that they were allowed to receive a dinner delivery.

The group began its sit-in on July 16 in response to the acquittal of former neighborhood watch captain George Zimmerman, who was found not guilty of second-degree murder in the death of 17-year-old Trayvon Martin. They have said they will not leave the Capitol until Gov. Rick Scott (R) convenes a new legislative session to reconsider the state's "Stand Your Ground" law.

On Friday, they were joined by singer and activist Harry Belafonte, who said in an interview with MSNBC that he was there at the disposal of the young demonstrators while expressing support for a boycott of the state.

"To boycott is an important thing for people to do. It touches the economic nerve," Belafonte told MSNBC host Chris Hayes. "It touches the way people are sustaining themselves. And if we interrupt the machine; if we interrupt the economic flow, then I think we can make a difference."
