Some residents are still out of their homes after an explosion rocked a Langley, B.C. townhouse complex Saturday morning.

Witnesses say the man who lives in the townhouse in the 8900-block of 208 Street was seriously hurt when the package he picked up on his doorstep exploded.

"Oh it was a big noise, really loud, shook the area," a neighbour tells CTV News.

Emergency crews, including the bomb unit, evacuated the area and blocked the road just in case someone had planted more than one bomb.

Const. Holly Marks of the Langley RCMP says area residents are safe. "Anything can be done is being done," she says.

By mid-afternoon, most residents were allowed home but others still had to stay away.

The 39-year-old from the townhouse was taken to hospital and is expected to survive.

Neighbours says the man had recently moved in, and was already moving out. A partially packed moving truck was seen in the driveway Saturday.

Four other adults were in the suite at the time of the explosion, but police say even with their statements, they don't have much to go on.

The victim has no criminal record, and police have no motive.
