This story was updated at 3:20 p.m. Tuesday

A 17-year-old River Hill High School student is now in stable condition after being struck by a car while walking to school on Linden Linthicum Lane Tuesday morning, said police.

The student, Matthew R. Curley, 17, of the 5800 block of Clipper Lane, Clarksville, was initially transported to the University of Maryland Shock Trauma Center in serious condition Tuesday morning, police said.

His status was upgraded to stable later Tuesday morning, police said.

Police said Curley was struck by a 1998 Honda Accord that was traveling westbound on Linden Linthicum Lane around 7:30 a.m. near Little Bells Row. Curley was walking in the crosswalk, according to police.

The driver of the Honda, who stopped at the scene, and a passenger, were not injured, said police.

The cause of the collision remains under investigation, police said. No charges have been filed.

River Hill High School principal Nick Novak sent out a letter to parents Tuesday afternoon notifying them of the accident.

"Although no students witnessed the accident, some students did see the police and EMTs responding to the accident and may be upset and concerned about the welfare of their fellow student," wrote Novak. "In addition, there was a lot of speculation on Twitter and Facebook about the accident. Please caution your children that they may hear rumors on social media that may not be accurate and let them know that our school support team will be available in the guidance office to assist students if they need someone to talk to."

This is the second serious accident in less than a week in Howard County involving a high school student.

In Ellicott City, a Mt. Hebron High School student, Jeffrey Sinclair, 18, remains in critical condition after his vehicle was struck by a Mack Truck as it was leaving the Mt. Hebron High parking lot. Four other Mt. Hebron students in the car at the time were not seriously injured.
