But after repeated complaints, the mother determined to examine the subterranean nuisance.

“It was a Friday, and my daughter, who is 21, called and she was panicking. And I asked, ‘What’s wrong?’ And she said, ‘Mom, I’m scared. The man told me I can’t walk right here and to just dip.’ And I’m like, ‘What man?’ And she was like, ‘The man in the sewer,’” Wiggins advised the outlet.

“I walk over to the little manhole sewer thing, and I hear somebody singing, and I think, ‘This is unbelievable.’ So I’m like, ‘Yo, yo, you,’ and he’s like, ‘What?’ And I said, ‘Leave my f–king kids alone,” she recalled of a confrontation with the unidentified man.

“And he said, ‘No, tell them to leave me alone’ And I said, ‘They can’t possibly be messing with you, and you are in the sewer,’” Wiggins said.

The sewer skulker even chased her youngsters down the avenue, prompting Wiggins to call the police.

Cops, however, advised her that sewers and culverts are public property, leaving their arms tied for options for kicking the man out of his underground house, the mother claimed.

“I don’t feel like I’m protected. I don’t feel like my kids are protected. I’m not saying this gentleman should necessarily go to jail, but he should not live in the sewer. He should not be able to be down there,” Wiggins said.

The involved mother said officers want to do more to defend her youngsters and the neighborhood from the belowground agitator.

“They can put a no trespassing sign there. They can put a no trespassing sign, and they can cover the holes. That’s what I would like to see. I would like Baltimore County to make me feel like I am a member of this community,” she said.
