Licensing — Driver’s license — Suspension — Refusal to submit to breath test — Request incident to lawful arrest — Finding that arrest preceded request for breath test was supported by competent substantial evidence where, although offense-incident report stated that licensee was placed under arrest after he refused to submit to breath test, the only two documents bearing specific time references showed that licensee was arrested at 1:01 a.m. and refused to submit to breath test at 1:20 a.m.
