Kenyan police have arrested the owner of a building that collapsed in the capital, Nairobi, last month.
The collapse has been blamed on poor construction and corruption
At least 20 people were killed in the building, which was under construction.
The arrest came after police placed notices in newspapers seeking help in finding businessman Nganga Kihonge, who disappeared shortly after the collapse.
Mr Kihonge could be charged with negligence, Criminal Investigation Department spokesman Gideon Kibunja told the BBC Network Africa programme.
Mr Kihonge was arrested as he left a hospital where he was being treated for injuries sustained in a car accident before the building collapsed, the AP news agency reports.
Earlier reports have suggested Mr Kihonge may face manslaughter charges.
Four Nairobi city council officials have already been suspended from their posts and charged with negligence. They have pleaded not guilty.
More than 100 people were injured when the building fell down on 23 January.
Shoddy construction and corruption in the issuing of building licences have been blamed for the collapse of the unfinished five-storey structure.
