What was that big explosion in VBT on Friday night?

Van Buren Township Public Safety Director Gregory Laurain said there were eighteen 9-1-1 calls within one minute’s time at about 8:40 p.m. Friday after a huge explosion shook windows and sent people out into the streets in northern VBT.
The calls came from the Ecorse/Mida Drive area to the north and Andover Farms to the south.
Director Laurain said the explosion seemed to be located at 8701 Belleville Road, the Belleville Manor mobile home park.
He said all the fire fighters were called out and police went into the neighborhood looking for signs of explosion, but found no smoke or odor and no debris.
Officers talked to people who came out of their homes after the explosion and were standing in the street, but there was no clue as to what had happened. Public Safety personnel were there for more than an hour investigating, Director Laurain said.
“It was significant enough to shake a lot of houses,” Director Laurain said of the explosion. He said by Monday there still was no solution to the mystery of what had exploded.
A resident of Crowley Drive emailed the Independent on Monday asking about the explosion that shook her house. She said her friends who live two miles away on Hannan Road also heard the blast.
She said it seemed to come from the direction of Belleville and Ecorse roads.
“We ran outside expecting to see a fire and cloud of smoke, but there was nothing but the sound of emergency vehicles. How
can the police not know what happened when there are reports of at least seven patrol cars, a firetruck, and two ambulances zooming down Belleville Road?” she asked.
