Footage shows the mother standing inside the construction site at Lenox Road and New York Avenue around 8:20 a.m., with another woman a few feet away cradling her baby.
The mom frantically screamed, “My baby! My baby!” according to workers at the site.
“[The good Samaritan] was trying to calm her down,” said site supervisor Schlome Stern.
Then she started “talking about marital problems, problems with her husband,” before collapsing to the ground, Stern said.
The video captured her lying on the pavement for several seconds before running away.
“When she heard us call the cops, she ran off,” Stern said.
Police brought the infant to Kings County Hospital across the street for observation.
The mother ran to the same hospital on her own, and checked herself into the psych ward, according to Stern and police.
“I didn’t expect something like this to happen,” Stern said. “It’s very sad but I’m very happy that there were nice people. And the cops were great.”
Cops would like to speak to the Good Samaritan who took the baby, though it did not appear that anyone would be charged Tuesday afternoon, police said.
