The son and daughter of a woman badly injured by a bus have called for a safety review of town centre streets.

Their mother was hit by the bus at the bottom of Station Road, opposite Greenhill, even though she was walking on the pavement near the curb.

Police closed the road for more than an hour and the London Air ambulance was called to the scene to treat the woman, who is in her 50s.

She was operated on to save her foot over the weekend and remains at a central London hospital in a stable condition.

The woman's son Saad Hassan, 28, who lives with her in Watford Road, said: “Its just been horrible. Thankfully she survived but it could have been so much worse.

“When we first heard she had been hit by a bus, we all feared the worst. Especially when we found out she had been taken to a major trauma unit.

“Being in the hospital has been an emotional time for all of the family.”

Mr Hassan’s sister Naina, 34, said: “We know this isn’t the first time there has been somone hit in the road and something needs to be done before something terrible happens.

“Something needs to be done about two-way system and the road itself, because the pavement is flush with the road surface.

“Even if they don’t change the two-way system, there needs to be some sort of railing there.”

Siobhan Freegard, who lives nearby and has raised concerns about road safety in the past, said: “When they first changed it to a two-way system I was shocked.

“No cars travel along there so people must think at times it is a pedestrian area like the rest of St Ann's Road.

“But with buses shooting up and down in both directions, the pavement full with school kids, parents and shoppers, it’s dangerous.

“There needs to be some sort of barrier next to the pavement to make it safer. It’s a matter of time until there is a really serious accident there.”

A spokesman for Harrow Borough Council said: “Clearly any accident is a concern and we wish the lady involved a full recovery.

“This area of the town centre is obviously a busy one with a lot of pedestrian movement, which is why we designated the speed limit as 20mph.

“The two-way bus operation has also been in operation for around four years with no particular concerns being flagged to us.

“However, we will look carefully at the police report into this accident to see if it raises any points on safety.”
