Ten weeks after the Stockline plastics explosion in Glasgow, the investigating authorities have returned the site to the company.

But the local MSP has criticised the firm for failing to keep the workforce informed about the future.
Patricia Ferguson said Stockline should have done more to keep employees informed about the situation.
Nine people died, five men and four women, when the plastics factory blew up in May.
Ms Ferguson told BBC Scotland: "There are criticisms that could be levelled. I think that it could have perhaps have been possible for them [the company] to have communicated in a more specific way with workers.
"However, I do understand that in the circumstances they have been very much affected by what has happened too.
"They have lost colleagues and have a number of their workers who are still tragically injured."
'Full and thorough'
Tonnes of debris have been removed from the site for detailed examination.
A Crown Office spokesman said: "The investigation into the cause of the explosion continues and the investigating authorities will continue to have access to the site when necessary.
"The handover marks the end of a 10-week process to recover vital evidence
from the site."
The spokesman described the investigation as "full and thorough" and said it
was not possible to speculate how long it may take.
In a statement, the company said: "We are grateful to the investigating
authorities for release of their properties on which buildings were destroyed on
11 May in tragic circumstances.
"The company is now endeavouring to reinstate plant, power, communications
and the orders at their Grovepark Street premises which are vital to the
progressive re-deployment of its workforce."
