Police were called to a reported robbery at 3:30 a.m. Friday at a residence in Packard Court.
The victim, a 50-year-old man, said he was sleeping when he woke up and found an unknown person standing over him in a ninja outfit. He said the suspect, holding a Chinese-style knife with a curved blade, told him in a raspy voice "give me all your money."
The victim said he reached down to his pants at his bedside and pulled out $600 cash and gave it to the ninja. He said the ninja locked him in his bathroom and left out the back door.
The victim said he then exited his house and called police from a neighbor's house.
