More than 170 people have been quizzed by police probing a gangland shooting outside a primary school.

Ross Monaghan, 35, was hit in shoulder when a gunman pushing a pram opened fire at the gates of St George's Primary School in Penilee, Glasgow, last Monday morning.

The shooter was seen wearing a woollen bobble hat, blue puffer jacket and pushing a children's buggy shortly after 9am after Monaghan dropped his child off at the school.

The hitman was spotted outside the school pushing the same pram three days before the attack, which is being treated as a targeted attempted murder.

Exactly one week on from the botched hit, officers returned to the scene on Muirdyke Road to speak to parents and drivers.

A spokeswoman for Police Scotland confirmed around 100 vehicles were stopped and 74 pedestrians spoken to and as a result officers are following a "number of lines of inquiry".

Police are continuing the major probe into the attempted murder and forensic officers last week pulled one of the stray bullets from a tree directly outside the school after recovering shells from the street on the day of the attack.

Monaghan was cleared at the High Court in Glasgow in May 2012 of the murder of Kevin "Gerbil" Carroll in an Asda car park in Robroyston.

He left Glasgow for Malaga in the Costa del Sol on Thursday night and pictures in a national newspaper show him pushing a trolley full of suitcases through the airport.

Officers say they still do not know what getaway car was used by the shooter or in what direction he fled the scene.

They say CCTV has captured a number of cars leaving the area at speed, however, and are trying to identify if any were involved.

Detective chief inspector John Kennedy told STV News: "The purpose of the exercise is to try to identify witnesses who bring their children to school, who were here last Monday morning just after 9am who may have witnessed the incident, who may have witnessed the gunman running away with the buggy and also to try to establish what route has been taken by the gunman and any accomplices.

"He must have got into a vehicle, he must have driven away at speed. We would have to assume that there was someone who had either attended in a vehicle or who helped him get away.

"We have picked up a number of cars on CCTV driving away at speed. We're trying to identify the registration numbers and identify the direction they have went.

"We are still trying to ascertain what kind of car the gunman got into to get out of the Penilee area."
