run into

No — say "I ran into my friend.". The phrasal verb takes the object directly after the particle without an extra preposition like 'with'.

Definition

phrasal verb. to meet someone you know by chance when you did not expect to see them.

phrasal verb. to encounter a person unexpectedly or by chance. The verb is transitive and inseparable, requiring a direct object.

contextual

“While I was walking through the park yesterday, I ran into an old friend from college whom I hadn't seen in years.”

complex

“It is not uncommon to run into former colleagues at these industry conferences, given how small the professional circle in this city remains.”

The object is usually a person you already know.

Contrast this with 'meet', which often implies a planned arrangement, whereas 'run into' is always accidental.

I ran into with my friend.
