A brazen thief has been connected to a dozen broad daylight bank robberies in Manhattan, where he made off with a total of $11,000, cops said Thursday.

The thief, who cops have identified as Joseph Rivera, has the same M.O. in all the robberies over the past month — the 48-year-old walks into the bank, hands the teller a note and demands money, police said.

Rivera’s crime-spree allegedly started just before noon on Sept. 6 when he robbed a Chase Bank on Bowery Street near Bleecker Street in Lower Manhattan of $1,000, according to cops.

Rivera’s biggest score came four days later when his midday haul totaled $3,700 from another Chase Bank on W. 23rd Street in Gramercy, cops said.

The thief was back at it on Sept. 19 when he tried to rob an HSBC Bank on Broadway in Greenwich Village — but cops said, he left empty-handed after the teller asked for his ID.

He tried again about an hour later and hit Amalgamated Bank on 3rd Avenue in Gramercy. This time, he only made off with $89, according to police.

The NYPD had a hard time tracking down the thief as he hit six other banks in other Manhattan neighborhoods — Midtown, Upper East Side, Upper West Side and Gramercy — due to the grainy surveillance videos, police sources told The Post.

It wasn’t until Rivera knocked over a pair of Midtown banks an hour apart on Tuesday — an HSBC Bank on 6th Avenue and a Capital One Bank on 3rd Avenue — that cameras caught a good shot of the thief, according to sources.

The NYPD released the new images Thursday afternoon and were still searching for the bank robber.
