Grammar fix
come forward
offer information or help
to offer to give information or help, especially when it is needed or asked for.
Hear it in context
Notice where the phrase sounds natural.
No one came forward with any information about the missing bag.
In my opinion, more people should come forward to support community projects, because it helps everyone.
Fix the pattern
One small grammar move makes it sound right.
Not: Witnesses came forward with to the police.
Say: Witnesses came forward with information. / Witnesses came forward to the police.
'Come forward WITH information' or 'come forward TO the police' — don't combine 'with to'.
Which sounds natural?
Tap the one a native speaker would say.
'Come forward' is the standard verb for volunteering info to authorities; the paraphrase is wordy.
