NEW YORK -- New York City police are looking for more suspicious devices after an explosion rocked Manhattan.
The blast went off in a dumpster around 8:30 p.m. Saturday on 23rd Street, between 6th and 7th Avenues.
Investigators are analyzing surveillance video, which reportedly shows a possible suspect.
Police are urging anyone with information to call their tip line.
29 people were hurt in the explosion, but most of their injuries are minor.
A second device was found near the blast.
Experts say it appears to be a pressure cooker, attached to a cell phone.
It was removed by a bomb squad intact, which means there could be finger prints.
