I'm not a lawyer but my interpretation of section 127 is the 'message' which caused anxiety would not be able to be proven false or that the sender knew to be false (since it's not a definitive statement about anything in particular, or in fact a message), and so didn't break the law. The alternative avenue is the police itself thought the material is of 'grossly offensive or of an indecent, obscene or menacing character' which would be next-level stupidity if the CPS actually agreed with.
