JERUSALEM (JTA) — Police are recommending that manslaughter charges be brought in connection with the collapse of a building at a wedding reception in Jerusalem last year.

The recommendation was made at the conclusion of a criminal investigation into last May's Versailles wedding hall collapse, in which 23 people were killed and more than 300 injured.

Police said Eli Ron allowed the Pal-Kal construction system to be used in the building, even after it was deemed defective by an Israeli building-standards institute. Police also recommended that charges be brought against Ron's assistant, the engineers who oversaw construction of the building and the banquet hall owners. It also suggested that Jerusalem municipal officials be investigated for alleged corruption for permitting the banquet hall to operate without the required licenses.
