Fraser home falling into the sinkhole.

A busted sewer line could be to blame for the sinkhole in suburban Detroit that was discovered on Saturday, according to city officials.

The sinkhole that caused 22 homes in Fraser to be evacuated on Christmas Eve has residents and business owners concerned.

The stretch of 15 Mile Road between Hayes and Utica roads is largely being blocked off by police.

Dean Rabhi owns the Amsoil franchise on 15 Mile Road, a few blocks from the sinkhole, and he's worried the road closure could have the same effect as one in 2004, when a sinkhole happened less than a mile away.

UPDATE 10:45 a.m.:

A suspicious package forced the evacuation of part of the Detroit Metro Airport today.

Mike Conway is an airport spokesman. He says baggage handling workers alerted security officials after a box containing electronic equipment and loose wiring entered the building. The box was being moved from one airplane to another.

Conway says the security officials closed 8 gates in the McNamara Terminal while they investigated the box.

 “The area below that is where the nuts and bolts where all the processing of all the luggage, packages and stuff like occur…this package was on a belt…in the bag makeup area for that section of gates.’"

Conway says the box did not originate in Detroit. He says the shipper is being contacted.

9:15 a.m.:

Part of a terminal at Detroit Metropolitan Airport has been evacuated, the Associated Press reports. Authorities say the evacuation occurred after a suspicious box was found at an area for loading cargo and luggage onto planes.  According to the AP:

Airport spokesman Mike Conway says the box was found about 7:15 a.m. Tuesday and passengers were removed from part of Concourse B at the McNamara Terminal out of "an abundance of caution." Conway says planes that were to use gates at the concourse were using other gates at the airport. The concourse at the airport in Romulus primarily is used by regional aircraft.

He says details about why security officials determined the box to be suspicious weren't immediately available.
