Can the police lie? Depends. Some jurisdictions release information about warrants while other don't. I imagine if your lawyer called the police they would either tell him you had a warrant, did not have a warrant or told the attorney they couldn't tell him. For example in Stanislaus County they won't tell me whether a person has a warrant but will tell a bail bonds company. So I have the bail company check.
Speak to your lawyer immediately. That is why you hired them.
The above information does not establish an attorney client relationship nor is it meant to provide legal advice.
I am not sure what your question is. You have an attorney you should be asking them for legal advice.
