18 Pa.C.S.A. §2711.  Probable cause arrests in domestic violence cases.
        (a)  General rule.--A police officer shall have the same
     right of arrest without a warrant as in a felony whenever he has
     probable cause to believe the defendant has violated section
     2504 (relating to involuntary manslaughter), 2701 (relating to
     simple assault), 2702(a)(3), (4) and (5) (relating to aggravated
     assault), 2705 (relating to recklessly endangering another
     person), 2706 (relating to terroristic threats) or 2709.1
     (relating to stalking) against a family or household member
     although the offense did not take place in the presence of the
     police officer. A police officer may not arrest a person
     pursuant to this section without first observing recent physical
     injury to the victim or other corroborative evidence. For the
     purposes of this subsection, the term "family or household
     member" has the meaning given that term in 23 Pa.C.S. § 6102
     (relating to definitions).
        (b)  Seizure of weapons.--The arresting police officer shall
     seize all weapons used by the defendant in the commission of the
     alleged offense.
        (c)  Bail.--
            (1)  A defendant arrested pursuant to this section shall
        be afforded a preliminary arraignment by the proper issuing
        authority without unnecessary delay. In no case shall the
        arresting officer release the defendant from custody rather
        than taking the defendant before the issuing authority.
            (2)  In determining whether to admit the defendant to
        bail, the issuing authority shall consider whether the
        defendant poses a threat of danger to the victim. If the
        issuing authority makes such a determination, it shall
        require as a condition of bail that the defendant shall
        refrain from entering the residence or household of the
        victim and the victim's place of employment and shall refrain
        from committing any further criminal conduct against the
        victim and shall so notify the defendant thereof at the time
        the defendant is admitted to bail. Such condition shall
        expire at the time of the preliminary hearing or upon the
        entry or the denial of the protection of abuse order by the
        court, whichever occurs first. A violation of this condition
        may be punishable by the revocation of any form of pretrial
        release or the forfeiture of bail and the issuance of a bench
        warrant for the defendant's arrest or remanding him to
        custody or a modification of the terms of the bail. The
        defendant shall be provided a hearing on this matter.
        (d)  Notice of rights.--Upon responding to a domestic
     violence case, the police officer shall, orally or in writing,
     notify the victim of the availability of a shelter, including
     its telephone number, or other services in the community. Said
     notice shall include the following statement: "If you are the
     victim of domestic violence, you have the right to go to court
     and file a petition requesting an order for protection from
     domestic abuse pursuant to 23 Pa.C.S. Ch. 61 (relating to
     protection from abuse) which could include the following:
                (1)  An order restraining the abuser from further
            acts of abuse.
                (2)  An order directing the abuser to leave your
                (3)  An order preventing the abuser from entering
            your residence, school, business or place of employment.
                (4)  An order awarding you or the other parent
            temporary custody of or temporary visitation with your
            child or children.
                (5)  An order directing the abuser to pay support to
            you and the minor children if the abuser has a legal
            obligation to do so."
