Factory death man named as inquiry launched
Police said a post-mortem examination carried out yesterday had proved inconclusive as to a cause of death.
The pathologist has decided to withhold his findings until the results from further tests are known,.
A joint investigation by Merseyside Police and the Health and Safety Executive is continuing.
The death follows an incident last December when two workers died after they fell into a machine at the factory.
In June, George Howarth, Labour MP for Knowsley, called for the site to be permanently closed down.
In a statement on Saturday, Mr Howarth said: "I'm deeply saddened by this latest tragic incident.
"It is barely three weeks since I said that 'as matters stand, I don't see how anyone can have any confidence in Sonae to operate safely and with stability'.
"It's too early to comment on the details about this tragic incident, but I sincerely hope that this will never happen again."
Sonae Industria manufactures chipboard and particle board for use in the furniture and construction industries.
