Cops have identified the man wanted for robbing a pregnant woman at knife-point at a Manhattan ATM — and said he threatened to cut out her unborn baby, police said on Tuesday.

Melvin Johnson, 49, pulled out a silver object and told the terrified 35-year-old woman he was going to cut her if she didn’t withdraw money for him, according to police.

Cops say she took out $400 in cash from her account and gave it to him before he took off on foot.

Johnson is described as about 6-foot-2 and weighing 300 pounds.

No arrest have been made, according to police.
