Stealing, in other words.
Not really. Stealing requires an intention to permanently deprive the owner of the item. The landlord would argue they aren't doing this as the items are just caught up in Evans not paying their rent and they'll get them back when the issue is resolved. In other words, it's not the landlord's responsibility to sort out items that only Evans knows the proper ownership of.
Anyway, it's shitty for all involved.
If the landlord has taken possession of the premises, by not letting customers retrieve their bikes aren’t they withholding property that isn’t theirs? Stealing, in other words.
