ROCKVILLE, Md. (WUSA9) -- A puppy snatcher is on the loose.

Rockville City Police say a woman walked into a pet store and acted as if she wanted to buy the Maltese puppy but instead walked out of the store without paying for it.  

The tiny pup was snatched from Just Puppies pet store in the Twinbrook Shopping Center, 2004 Viers Mill Rd., in Rockville, at 5:30 p.m. on April 12. 

Police say it was caught on tape. They say the woman is seen holding the puppy in the playroom and when she sits down stuffs the Maltese in her purse and walks right out.

Mara Fain was helping the woman out that day.

"I was helping other customers and she just disappeared. I've never seen anything like it."

Employees never suspected the woman. But now they're worried about the health of the puppy that's about 2 months old and under 2 pounds.

ROCKVILLE, Md. (WUSA9) -- The driver of the Ride-On Bus accident that caused a eleven-car pileup on Monday in Rockville has been cited. 

Montgomery County Police say 58-year-old Walter Eugene Pardy was cited with failure to reduce speed to avoid a collision. 

It happened on Nicholas Lane just before the Rockville Pike. The cause is still under investigation, but it appears to be one of two things. 

Either the brakes on the bus failed or the bus driver wasn't paying attention. This was a red light. There were lots of cars stopped here at the intersection. And this Ride On Bus just plowed right thought them. 

One witness said, "He just never stopped. No brake lights. No nothing. Just ran into all the cars."

Terri Ferrara was on her way to a job interview when her car was one of eleven taken out by this Ride-On Bus. 

"He was moving fast...I am a little shaken. Kind of numb."
